AWESOME for warm weather hiking!

I purchased these in the algae green. I will say I was pleasantly surprised when I took them out of the box that they are a bit more muted in color than they appear to be on the website. I would say the green is similar to the greens people wear in hospitals. Also the white sole is not bright white, it is muted. And they smell good! Kind of like cotton candy.

I had a hard time determining the size and I was lucky enough to guess right. For reference, they are the exact same size as I wear in Birkenstock sandals. So I would recommend trying on some Birk sandals to figure out your perfect size.

The first time I wore these outside I worried I would end up with blisters. It was crazy hot and I went walking with a friend for an hour. My feet were pleasantly surprised, no blisters, rub spots, or anything! Just happy feet!

I wanted these mainly as a cool (as in breezy) option when hiking in hot weather, but I also am planning on taking them to a beach vacation later this year. They are advertised as water shoes, but if you are looking for a minimalist hiking shoe, these are great! I have other Vivo shoes and they don't grip well, but I feel like I have frog feet with these on. They have better grip than my regular hiking shoes! Even better, there are little indentations inside the shoe that your feet stick to, so when I am going down steep hills, my feet stick to the shoes and my toes do not jamb into the front of the shoe.

Of all the barefoot-type shoes I have ever worn, these are the most comfortable and give me the truest barefoot experience.

I will say that because of all the holes, dust does tend to accumulate in them, and so my feet can get kind of grubby. It is easy to rinse them off though.

I don't think I would like them for true beach shoes if I was walking through deep sand. I would imagine the sand would accumulate in them and drive me nuts. BUT, really, if I am walking in deep sand, unless it is really hot sand, I would much rather be truly barefoot anyway! I think if you are walking through streams, that kind of thing, these are probably excellent.

THANK YOU, Vivobarefoot, for making these comfortable, minimal, cool, and simply awesome shoes!!!

Wonky Sizing

I got these for my wife and they are, in her words, "super cute." The negative review is only because each shoe was noticeably different in size. You could see it with the naked eye and she could definitely feel the difference. Both said they were size 7's though, so I'm not sure what happened. We returned them for a pair of black (less cute but no more green in her size) and all is well. So maybe we just go the weird one. We love Vivo's.

My daughter loves these!

Got these for my 9 year old and she picks them above all her other shoes! They did rub on the back of her heel for the first couple times but after a couple of wears she has had no problems. She already has her eye on some other designs. Thx!
