I have two other pair of Merrell Barefoot shoes.  The thing is, it's the devil's own work to put them on, you need a cat burglar to actually slip your feet in...then....oh my.  You are truly barefoot but with really really tough feet.  You can walk over stones, climb trees, ride horses bareback.  Your little toes go "Wheeeeee!"  It's totally delightful.  But wait, there's more!

These guys hurt, right smack dab where the shoe creases as you walk.  I've worked around it, because they are so expensive I want them to be right.  Perhaps in a few weeks, a bunch of miles later...

Nonetheless, hurt aside, you can climb Mount Everest in these guys. You DO NOT SLIP.  So, if a certain degree of pain is not offputting, go right ahead because you sure as heck can run slide grip grab, and you WILL NOT FALL.
