I have not worn them for anything but walking around yet, so this is preliminary. However,I mainly got them for casual use and keep these as my "pretty" don't get them yucky shoes. http://xeroshoes.com/shop/feeltrue-products/sensori-venture-womens-barefoot-sandals The slip ons work well right out of the package. The styling and construction looks professional and strong. The sizing guide got me the right size. The colors are sporty; the sandals have a cleaner look than the DIY kit. The soles are thicker than they need to be. Not sure why. 5mm I think? Huh. Not a big deal, I guess, but I don't know why they couldn't go thinner. Again, I don't plan on running in them much, but I will try. Biggest complaint: HEEL CUP. WHY? A little raised rubber part at the back of the shoe, for no reason. I'm not sure if it would bother me while running, but I can feel its existence walking around in them (my primary planned use), and it serves no purpose. I can imagine it pushing rubbing on my heel uphill or downhill. Again, the huarache design never had a heel cup. If I could pay an extra $5 to have them removed, this sandal would be great for casual wear.
