Love this shoe! It is light weight, cushy and supportive. I am diabetic and, at only 60 years of age, I have chronic back, neck and pelvis issues as a result of two high speed rear ending auto collisions and walking very far can be painful and challenging. I have lots of Merrell shoes, but when I've got to be on my feet and walking for a while these are now my favorites. These Ultras with 12mm cushioning, instead of the usual 4mm, plus the strong support for my high arches and their extreme lightness allow me to go farther before my lower back and pelvis start screaming! The wide, roomy tow box feels like it was specifically designed for my wide feet and curved, slightly hammered toes with plenty of wiggle room and no rubbing concerns. The barefoot profile is so much better for someone with mild diabetic neuropathy, like me, and enables me to have a better sense of the terrain under me than the standard Merrell profile. Socks are problematic for me and these Ultras are washable and without seams or connecting points that cause rubbing or discomfort - so I wear them sans socks! I would purchase more of these shoes if Merrell would increase the color choices!
