Castelli T1 3 Sock

The T1 Sock has been engineered with an exceptionally high stretch cuff that opens wide and is easier to pull over your foot when you’ve just come out of the water. The CoolMax®/Lycra® blend is especially slippery on a wet foot which helps getting it on, as well as helping to reduce friction during the run. So now with no time loss you can put your sock on in T1 and have that extra foot protection on the bike so your feet will stay protected for the run.
