So far these shoes are amazing. everything i was looking for My size with a regular Loyak 10 turned out to be too big. I'm a size 10 1/2 and the Loyak AC 10 fits perfectly. Easy to turn on and off. Initially they were too tight and rubbed the top of the left big toe almost to the point of wetness, loosened the laces a bit and now they fit like a glove.
