Cool Shoes

Just took these to the Yucatan Peninsula in Mexico and wore them exploring a lot of Mayan Ruins and Cenotes. Love the look and feel but after a couple weeks and one long day I started to develop a blister wear they rub on the back of the achilles tendon area. A little harder to put on than other vivo shoes. I would recommend these shoes.

Love these shoes

I absolutely love these shoes! I first I thought they were too big because there was so much space between the front of my shoe and my big toe, but thankfully the customer service person said that was normal. I truly felt Barefoot wearing these across Costa Rica. They're supportive and light at the same time. I'm recommending them to everybody! I'm realizing that some of my other shoes crowd my toes and will slowly change my shoe wardrobe for healthier options!

Super Versatile

I really wanted these to work, but I think I'll have to order the next size down to be able to wear them with no socks. The blue is beautiful and eye catching. It's the perfect hiking shoe for dusty California trails. I made the mistake of wearing my white Primus Lites on a trail and am glad to be able to have a fresh pair to use.
