I picked up the Squid Socks Caffeinated Grip Socks in the no-show height and they have become my go-to for training. The S-GRIP dots really do cut down on heel slip, so my foot stays locked in during quick changes of direction. The cushioned toe and heel plus the seamless toe keep things comfortable, and the bamboo blend breathes well and manages moisture. One tip: the no-show style runs a little small, so size up if you are in between. Gentle wash, no bleach or tumble dry.
