The 6th version of Merrell's famous minimalist shoe is designed to mimic the shape of the human foot, keeping it in the position it would be in without shoes. Version 6 features an improved fit and increased abrasion-resistance. Compared to the prior version, Version 6 features a little additional support, a slightly thicker sole, and increased abrasion-resistance. It’s a great option for someone looking to transition into barefoot styles.
