Most socks for cycling, e.g. Swiftwick, I tried do not have enough padding on the bottom and I feel it on long rides with stiff road shoes. However, I’ve found deFeet Cyclismo pretty good. Apparently, Cyclismo was originally made under the direction of a World and Olympic Road Race champion who wanted some cushion under the ball of the foot. I have a low volume foot, so the fit is great for me.
