Review on Saucony Endorphin Speed Running Shadow: Unleashing Unmatched Speed and Endurance by Sam Lund

The shoe is tight around the ankle but leaves enough room for the rest of the feet. This is very good for pace, intervals and long runs. Although the shoe is very light, it offers enough cushioning for cushioning and stability. When you first run in running shoes, you may feel like you are "jumping", so it may take a few runs to get used to it.
