👇Check the size chart. We recommend ordering one size larger than your usual size.
In the table below, you will find the shoe size we recommend for you based on the length measurement of your foot.
So, you only need to know the length of your foot in centimeters. Here’s how to find it out:
Measurement tip:
Place a piece of paper on the floor with one edge against the wall.
Put your heel against the wall and mark a line on the paper at the tip of your longest toe.
Measure the length from the edge of the paper to the line you drew.

Your feet were born to run — Lento barefoot running shoes let them run naturally
Vaistoa Lento is the first barefoot running shoe designed in Finland. Built for the demands of running, it stays true to the core principles of barefoot running shoes — natural movement, zero drop and unrestricted function.
The Vaistoa Kenno™ outsole follows the natural anatomy of the foot and provides exceptional ground feel. The wide toe box allows your toes to move freely, while the heel structure, upper and lacing are designed to keep the shoe breathable and securely in place.
At just 205 g (size 40), Lento is so light it fades away after just a few steps. Soft upper that moves naturally with your foot — no pressure, no rubbing, no awareness of the shoe. Just you, your stride and the ground beneath you.
Barefoot running isn’t for everyone. It requires adaptation.
It’s for those who want to learn to run the way the human body is naturally designed to. For those who want stronger feet, better ground feel and a more natural running stride.
The beginning isn’t easy. But as your feet adapt and your technique improves, there’s no going back.
Start gradually.
Barefoot running requires technique, mobility and strength. If you don't yet have control over a forefoot or midfoot strike, focus on building that first.
Begin with short distances — often shorter than you think. Softer surfaces are a good place to start.
Shorten your stride, increase your cadence and bring your step underneath your body. Aim for around 180 steps per minute.
As your technique stays consistent, you can gradually increase the distance.
We offer a 90-day FREE return policy. You can try on your shoes at home and ensure they are a perfect fit for you before you start your Vaistoa adventure. If you're not completely satisfied, simply return them within 90 days for a full refund. No questions asked.
For detailed information about our return policy, please follow this link.
MEASUREMENTS:
Weight: 205 g (size 40)
Insole thickness: 5 mm
Sole thickness: 4.5 mm
USAGE
Loosen the laces properly when taking the shoes off and putting them on. This reduces wear and helps extend the lifespan of your shoes.
Let the shoes air out well after use. Fully loosen the laces, remove the insole, open the shoe wide, and allow the shoes to dry naturally before the next use.
It’s also good to give your shoes “rest days” so they can dry and ventilate properly.
CLEANING AND STORAGE
It’s best to clean off loose dirt right after use with a damp cloth or sponge.
We do not recommend washing barefoot shoes in a washing machine. The membranes of waterproof models may become clogged, and machine washing can weaken the durability of the shoe’s glued parts.
Store the shoes upright at room temperature and protected from UV light.
Enjoy every step and every trail!

There are very few barriers to using barefoot shoes.
However, such barriers include functional or structural disorders of the feet or lower limbs. For example, hallux rigidus, or stiff big toe, where the big toe joint does not bend easily or at all upwards during the push-off phase of the step – which is a requirement for the natural roll of the step.
Similarly, any surgical operations where joints are fused – that is, their movement is restricted or completely prevented – pose challenges for the smooth use of barefoot shoes and the benefits they provide.
Loss of sensation in the soles of the feet (neuropathy) due to diabetes or nerve damage can also be considered a contraindication for using barefoot shoes, as you may injure your feet without noticing through the thin sole of the shoe.
If you have painful osteoarthritis or an active inflammatory phase of rheumatoid arthritis, it is advisable to reconsider using barefoot shoes until the condition improves.
If necessary, consult a physiotherapist or podiatrist who is knowledgeable about this matter. Remember to tell them that you want to transition to using barefoot shoes and ask how they can assist you in this project.

Brilliant everyday and work shoes. I haven’t tried them for running, but they’re excellent for walking.
My first pair of barefoot shoes. They’re lovely to walk and run in – and they’ve got surprisingly good grip, even in the woods! I went for a size larger.
I love these shoes. I was looking for something wide enough for my pinky toe, and these have a really good fit and are very comfortable. I was just in-between a size 38 (which is normally my size) and a size 39. I went with the 39, which I am glad I did since I use them for running, and I think a 38 was going to be a little too tight. Now I am just waiting for Vaistoa to make a pair of biodegradable trail running shoes with more grip.
The perfect running trainers! Lightweight, grippy and so comfortable on your feet that you don’t even notice you’re wearing them. Even afterwards, no pain anywhere from poor posture – though I did run so hard that my muscles are really feeling it! 😉
I needed some new running shoes and was torn between basic trainers and performance trainers. Luckily, I ended up going for these – they’re really comfortable, well-made and supportive, without being too cushioned. The knee pain that used to flare up a bit when I wore standard trainers has gone. They fit my feet perfectly and are great for both walking and running in the woods and on the running track. :)
I was looking for a versatile pair of trainers. Years ago, I bought a pair of ‘Vaistoa’ barefoot shoes, but after the initial enthusiasm, I ended up wearing them less and less over the years because I could often feel stones through the soles, which was rather uncomfortable. Vaistoa I think the sole is a touch thicker, so the stones no longer feel bothersome in these, and they’ll be in constant use!
Olen ollut uskollinen Vivobarefoot- käyttäjä, mutta uskaltauduin kokeilemaan Vaistoaa. Voin sanoa, että kokeilu kannatti. Juoksu ja kävely sujuu hienosti uusissa ja hienoissa juoksukengissä.
A good purchase after a moment’s thought, as I already had almost every other model of barefoot shoes. The slightly thicker sole on these shoes is more comfortable when running on a forest track covered in large gravel. I no longer need to avoid those spots as much, as the stones don’t feel quite so sharp through the sole. They feel very comfortable on the feet in general, too.
These have been the best purchase ever. I’ve been out running in regular trainers and barefoot summer shoes. One pair is too tight and the other is just too light. This barefoot running shoe model stays comfortably in place thanks to the laces. Absolutely the best purchase. Thank you.
I’ve already got a pair of Vaistoa Uljas zip-up barefoot trainers
! I love wearing them in the woods ! In the spring
I couldn’t find any trainers, so I got Riku’s Vaistoa ! The best shoes in the world, especially for a run in the woods
And elsewhere too, of course! My toes are so happy – my whole body feels great
. My spine’s straighter! Not so great on tarmac, though! I love the woods
Not city life! Thank you all! If only barefoot shoes had been around sooner! You can get plenty of exercise with spikes 😉
Great shoes and an excellent shopping and customer service experience. Thank You again Salla! Vaistoa stand behind their products and refund gaurrantees and as importantly produce excellent, stylish shoes that are a pleasure to wear. The lento is likely my 5th or 6th purchase from Vaistoa and again I am delighted. I highly recommend these, great for running and gym work. Thanks.
Hi I ordered the Lento after a couple of tries to find the best running and gym shoe - these are it for me, just brilliant. I want to say kudos to Vaistoa (especially Salla!) who helped me through a refund process and guided me on size choices. for reorder I was guided to go one size up in this model. I will admit I was sceptical but the advice was spot on the 45 fit my normally size 44 foot perfectly with exactly the fit and room for gym work, running and general wear I needed. The shoes are great but also it is so rare these days to find a company who really stand behind their product and provide great service as well as products. Well done Vaistoa, keep it up I will order again soon highly recommended - can we have a white version of the lento soo? best Tony
I tested the running shoes on sandy and gravel paths, forest trails, boardwalks and rocky terrain – they felt as light as a feather, the grip was brilliant and they made my whole body feel absolutely great. Thank you!
-Tuulia
You can actually run in these! They feel like barefoot shoes, but the stones don’t hurt the soles of your feet quite as much as they do with standard barefoot shoes.
These shoes feel really good on my feet 👌🏻 At first, I ordered the size suggested by the measurement tool, but I didn’t trust the recommendation… so I returned the ‘small’ ones and ordered the right size 👍🏻
I haven’t tried them out whilst running, but they’re really comfortable for walking.
As running shoes, these are really comfortable, yet firm and well-fitting. They’re also suitable for trail running and cycling. I went a size up as advised, and that was exactly the right size.
They’re stylish too, standing out from basic trainers in terms of shape and design.
They feel really good on your feet and are surprisingly supportive. I tested them on tarmac, a gravel track, sand and exercise steps. I don’t run myself, but I do a lot of walking. I’d recommend them to anyone who enjoys being active. 👍
These barefoot shoes have helped relieve my lower back, hip and knee pain. I used to wear other barefoot shoes when out walking, but these are considerably more supportive and therefore provide a more secure stride.

They feel really comfortable on my feet and are excellent for running; I also use them for walking. They stay securely on my feet and the stride feels comfortable. I’ve been wearing PJ shoes for several years and have been looking for good running shoes – and now it seems I’ve finally found them! It would be a bonus if the shoes were waterproof; they get wet straight away if the ground is damp. The size is just right; I chose it according to the size chart. Hopefully they’ll be durable, as these have definitely become my favourites!
The only complaint I have is that the back edge of the shoe that rubs against the akilles tendon was to high and to hard so I got a blister, Had to elevate the heel 2 mm and then it was OK but lost the 0 drop idea .
Thanks
Bring on the summer – the new Vaistoa Lento shoes have arrived, along with some new trainers… They’re incredibly comfortable and fit my feet perfectly, just as Vaistoa shoes always have. The best shoes for summer dog walks. My running partner likes them too!
For me, the challenge with trainers has been how they feel around the ankle and heel, as I have a total of five scars on my right ankle – around the heel bone and on the top of the foot. They’ve largely dictated what shoes I can wear. (I may have neglected treating the scars a bit too much about 10 years ago…)
In these trainers, the support around the heel is just the right amount of firm yet wonderfully soft for me, so even my right foot gives these shoes the thumbs up!🥳
I don’t know about their running performance, but they’re really comfortable and light on my feet when I go for a walk. They don’t pinch or feel tight; it feels as if I’m not wearing any shoes at all. The tread pattern provides good grip. A perfect ten, just like all the other shoes from Vaistoa.
They perform brilliantly when climbing rocky terrain and on challenging forest trails, yet you don’t even need to go for a run to appreciate how comfortable they are. The design and tread pattern of the sole are a real improvement on previous models.
No need to worry about what to put on your feet. Thank you.
I’ve been breaking them in and my back’s still a bit stiff, so I haven’t dared to go for a run. They’re really comfortable – lovely to wear. Even today, during dog show training, I was on my feet for a good hour and my back didn’t get too sore. I’d recommend them.
Really good, comfortable running shoes. Suitable for both running and long walks. I’ve mainly used them in the woods and on trails, and they’ve been a brilliant choice!
Best shoes ever!! Really! Comfort snug around your foot, not like other barefoot shooes might feel sometimes like a ” bag ”. I Will definitely recommend these shoes and I will buy another pair as soon as they come in more colors. The little thicker sole are very comfortable!
I have 5 other pairs of barefoot shoes and can’t compare them with these
The recipient of the gift says that the shoe is comfortable to wear. There is plenty of room for the toes and the heel sits securely. The shoe is easy to put on and the laces are of high quality. The outsole appears to provide good grip.
The shoes have been tested on a nature trail, a sandy track, tarmac and a running track.
Very cool and nice shoes for the gym. The sizing in those is a little shorter than all my other vaistoa (4 different). But I think they would be too big if I ordered a bigger size. So I hope they work well over time.
Barefoot running shoes allow your feet to move naturally and your body to take a more active role in each step. This can improve balance, strengthen the feet and support a more natural running style over time. However, running in barefoot shoes feels different at first and requires proper adaptation.
You can test the shoes indoors for 90 days. Returns are free, so you can order risk-free and with peace of mind. If you're not completely satisfied, simply return them within 90 days for a full refund. No questions asked.

It’s important to start gradually. Your feet and running technique need time to adapt. Begin with short distances and increase your running volume step by step. This allows your muscles and connective tissues to strengthen and helps reduce the risk of overuse.
Barefoot shoes have been around for years and are based on principles of natural movement and foot health. They are not just a trend; they are a step towards healthier footwear choices.
Our barefoot shoes are made from high-quality materials and designed for use in various environments. They are durable, but it’s important to remember that all shoes are consumable items. Barefoot shoes naturally have thinner soles compared to traditional thick-soled shoes. The durability of the soles can vary depending on the level of activity, the environment, and your walking style.
While athletes and outdoor enthusiasts use barefoot shoes for their features, they are suitable for anyone looking for comfort and the benefits of natural movement.
Many people with foot problems have found relief with barefoot shoes because they improve foot functionality. However, it’s wise to consult a healthcare professional before making a change if you are unsure.
Barefoot shoes do not provide any support because their purpose is to allow the foot muscles to work while moving. Supported shoes weaken the foot muscles because they don’t get to do their job.
Our customers have reported numerous benefits from using our barefoot shoes, such as:
