I tried these on a couple of hikes, for use as a camp shoe, for swimming and creek crossing, etc. But I soon gave up on them, not just due to the poor sole protection and the lateral movement that were cited, but also due to dirt and gravel quickly getting into the sandals (drier conditions) and water (wetter conditions). The lightweight simply wasn't worth it to me. I recommend something sturdier unless you have ideal trail conditions and feet that can handle the stress. Added: Try "Gold Pigeon"… Full review
Xero’s Z-Trail is a minimalist sandal in a number of ways. The sole and midsole together are less than a centimeter thick, with no thick heel or arch support. They secure your feet with a hook and loop heel strap and a continuous polyester strap that you pull to tighten. They are unexpectedly good at protecting the soles of your feet for such a light and flexible sandal, and traction is very good to excellent.

The closest thing you can get to nothing, without actually having nothing. A perfect shoe for marathons, ultra marathons, camp sandals, beach sandals, lounging, or trail running. The literal "do everything" sandal. Build your own here Note: Although my review is very honest, i am an Affiliate. If these minimal sandals do not work, there are many other styles and shapes for different purposes. All are built upon the same idea of the Huarache, however some are built with thicker souls, bells and whistles… Full review
A very lightweight camp shoe, with no frills. For several years, I've used a pair of old Teva sandals as camp shoes for backpacking trips. They're relatively comfortable, not too heavy, and seem nearly indestructible. But I am always looking to lighten my pack weight, and these caught my eye. Xero is a newish company specializing in "barefoot" style running sandals. The soles are thin, and designed to feel everything underfoot, while still maintaining some protection against sharp things. The good:… Full review
Very light on your feet with firm hold, more stability for your heel than for the forefoot. But they are very comfortable. But I think overall you have to be made to use the sandal, not the other way around. You can't wear them everywhere like in a Mexican outing. They have nasty thorns that could easily puncture the shoe. Feels great to wear though. Full review
Xero Shoes, which makes barefoot running sandals, was originally called Invisible Shoes.
