After receiving a recommendation to try your products by my acupuncturist who is treating my Morton's Neuroma, I have to admit he was more than right! I don't think I can go back to other shoes now!

For years I have struggled to find shoes that are wide enough for my little hobbit feet. As a personal preference, I also prefer shoes with maximum flexibility in the sole, particularly for running. I haven't found shoes (until now) for the past decade and these couldn't have come into my life at a better time! I finally blew a hole in my last pair!

Out of the box, these fit beautifully and true to size although I couldn't afford to have them any more narrow. As someone with wide feet, I also have an incredibly high arch which makes me unable to use the insole (which is a bummer) but fortunately, due to the intelligent design of the shoe, I don't feel they are a necessity. The only upside for me using the insole would be for insulation, my toesies got a little cold running while there's still snow on the ground but that's pretty minor. I didn't have any neurological pain in my feet after running 5km which is impressive for me! I love the speed laces, they make it a breeze to cinch them to create a custom fit and don't allow any lift in the heel (as someone who's also suffered from Achille's tendonitis from poorly fitting shoes). Tread provides great traction on most surfaces/conditions (not on ice but they never claimed to be suited for that)

Perfect, perfect shoe! I cannot recommend them highly enough, particularly if you have wide feet &/or high arches like yours truly! Worth every penny!

Great Shoes

These shoes are so comfortable, soft and light. I have used them to walk in the city, in the trails and even at the gym.

I love these shoes

Firstly you notice the light weight of these shoes, they feel like a feather in your hand. Wearing them is joyful. They give my feet so much room and are so comfortable to wear. I really want all my shoes to be Vivobarefoot now. I haven't used them with the optional insole yet and this might offer a little more cushioning. They also come with laces which I might try as the toggle is quite stiff, although convenient. Thank you.
