Great Product

One of the best purchases I’ve made so far. It’s great for all my Movement practices. However, they say it’s true to size but since I don’t have wide feet, I had to get a size smaller. I’m usually a 9 and I got and 8.

Took some time to fall in love with them

I was super excited about these shoes because they look so great. First time I tried them on it was weird. They felt uncomfortable in the front part of my feet and also were a little too big (I usually wear 8.5 Nike/adidas and ordered 8 from vivobarefoot). I still wanted to give them a chance before returning because I had to pay for returns (I wish you guys had free returns for the US!). Here is what changed my first bad impression- I used insoles (they came with the shoes in the same box), and wore my vivobarefoot with cushiony socks. Also, (it sounds obvious but it really helped) I loosened the shoelaces and made sure they are loose around the front part of my foot. I honestly don’t tighten them at all because the shoe is pretty tight around my ankle. After wearing them for 3 days I finally started enjoying them. Now I wear them without socks too and I don’t have any discomfort I had first time I tried them on. I went for a 10-mile hike in my vivonarefoots and it was amazing. I also wore them in water and they squeak for a while after you exit the water and start walking on a dry surface but I assume this is the case for any shoes. To summarize, I really like my swimrun vivobarefoot, will mostly use them for hiking because I still prefer to have more support while running, but i’m definitely going to keep them.

Great toe space

These shoes are extremely comfortable! However, due to the height on the back of the heel, I have developed some painful blisters after my runs. I love the width of the forefoot and toe box, and I am able to wear my Correct Toes with no problems in them.
