Named after Legendary ultra marathon runner Karl Meltzer, the Speedgoat is a maximally cushioned shoe for a beautifully soft run and it excels over long distances. There is a pronounced meta-rocker in the forefoot to help smooth out your stride, and the Vibram outsole is superbly grippy on both hard and soft surfaces. This new version has an improved upper for a better fit and breathability. We recommend getting this shoe in half a size bigger than your normal running shoes.
