The 6th version of the famous minimalist shoe is designed to mimic the shape of the human foot, keeping it in the position it would be in without shoes. Merrell Men's Trail Glove 6 Running Shoes feature an improved fit and increased abrasion resistance. The Trail Glove 6 is a barefoot shoe and has been built with a full forefoot to allow for a more natural foot movement. When compared to the Trail Glove 4, it is running ½ size large. If you're looking for a similar fit to the previous Trail Glove 4 version, Merrell recommends you order a size smaller than your typical size. When compared to the Trail Glove 5, sizing is the same.
