I picked up the Squid Socks Back to Basics Grip Socks for pickleball and they've held up well. The S-GRIP grip zones really do cut down on heel slip, and my foot feels locked in during quick direction changes. The L/R labeling and Y-stitched heel give a snug anatomical fit, and the cushioned toe and heel plus blister tabs are a nice touch. Bamboo blend is breathable and moisture-wicking. I sized up as advised and it worked out. Gentle wash only, no dryer.
