Tried on only, never used for running. Topo Athletic MT-4 M Men's Size: 27.0cm Retail Price: ¥23,100 ■ Brand Topo Athletic ■ Model Number 020045-85 ■ Product Name MT-4 M ■ Versatile all-purpose trail shoes The upper, which combines stability and durability, uses recycled mesh material equivalent to three 16oz (approx. 470ml) plastic bottles per pair. There is a drainage port on the inside to quickly release water and dry. The dual-density (two different densities) midsole provides a softer feel underfoot and a firm response to the ground. The outsole is equipped with Vibram XS Trek, which enhances traction and durability on various terrains, and the moderately spaced lugs allow mud and snow to escape. Includes gaiters PERFORMANCE GAITER Performance Gaiter Size: LG (26.5cm~) (Price: ¥5,300) How to use: The gaiter's hook is attached to the shoe's loop for fixing, allowing the gaiter to be easily attached and detached without removing the shoes. The gaiter is securely fixed by three fixing hooks provided on all trail model shoes. I have another pair of TOPO shoes, and I will include these (versatile gaiters).
