I like the one sided tongue, love the outsole, I thrive on hiking in this shoe but I find that when I run I get hot spots and rubbing on the ball of my foot and ankle more than other Altra running shoes. I ordered size 11 because I have 4 in Torin and Escalate 11, some people said Superior can be worn without socks, tried this, wore my Achilles tendon down a mile so won't be doing it again. I like these shoes best, but I liked my individual visors more.
