I've been running on Merrell Mix Master Move Glide shoes for about a year and a half, so I decided it was high time I wrote a review. I just finished an 8-mile run on technical hilly trails in my brand new pair. These are my third pair. I have only good things to say, so here are my comments: The soles are nearly minimalist, but protect feet from sharp objects and cold weather. There is enough support, yet I can still feel the earth beneath my feet, which I enjoy while out in the wilderness. The traction is phenomenal. In the hundreds of miles I've run in these shoes, I have never twisted my ankle by slipping on a root or stone. The uppers are light, breathable, and comfortable. I have a bunion on my left foot and the toe box is roomy enough to accommodate with no pain. They run true to size for running shoes. I normally wear a size 7.5 street shoe and a 8.0 running shoe. I purchased size 8.0 and they fit perfectly. Thank you Merrell, for another great shoe.
