I am very surprised at the poor design of this shoe. If you use all the eyelets when lacing your shoe it is next to impossible to tighten the shoe and if you pull too hard you can see and hear the material breaking down. The sole is extremely thin and unusually pliable. I could cause the sole to scrunch up simply by scrunching my toes. The shoe has very little, if any, arch support. Also, the outside portion of the shoe is built-up more so than the inside and causes your ankles to roll inward, thus giving poor alignment. I guess the upshot is that your ankles won't roll outward. I strongly do not recommend "All Out Defy" to anyone. I have returned my shoes and am expecting a full refund. I am so disappointed that it has given thought to never making a Merrell purchase again.
