I ordered these after much research on YouTube and reading reviews. With the return policy I knew it was a risk free trail as long as I didn't wear them outside. A little background on my feet: Left is 9, Right is 8.4. So I was hoping they wouldn't slip in the right heel. I was could hardly wait for my package to arrive, when they did, only a few short days after ordering, super fast. I Definitely Love Their Customer Service, I strapped em on my feet, with only a pair of R.E I. merino wool light hiking socks, I wear these with all my foot wear except when I go snow camping. After tying them to my feet and walking around for I guess 5 mins, I decided to buy them and immediately went for a 5 miles hike through Granite, Sand, Dirt, Grass, Boulder Fields, Up Hill and Down Hills, My toes didn't get smashed in toe box going downhill either, the heels didn't slip going uphills. I was stoked to get home and the next day I went for a 9 mile hike same terrain. I waited a few days and went for a 15 mile hike, that was on a Friday, Monday I did the same 15 mile hike, when I got home, I was tired and all my muscles hurt. I showered, ate and slept for 3 hours woke up I was fine. Today I went for a 20 mile bike ride out to the lake, and around the river trail. These Boots are Truly 100% The Best On The Market.
