GRPZ Marathon ELITE
Built for distance. Designed for the final mile.
GRPZ started with athletes losing grip inside their shoes. Over 26.2 miles, that same small movement repeats tens of thousands of times. Every slip becomes friction and every friction point becomes a blister by mile 18.
So we took the grip out and built the hold into the sock itself.
A hot spot at mile 18 is enough to change your stride for the last eight. When the sock disappears, all that is left is the run.
