The W Nike Acg Pegasus Trail shoes at first felt very stiff and the back heel felt bulky, however, after trail running the first couple of times, they really softened up. They had nice cushion and I felt zero pain in my knees or shins, which sometimes happens. The fabric was breathable and lightweight. The design was simple, all black with a few details like speckled laces and a unique ACG logo. I would have preferred a little more rugged, edgier details for a trail shoe.
