Marathon ELITE Crew Sock

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.

• Merino blend: Regulates temperature from the start line chill to the final mile.
• Seamless toe: Nothing to rub over 26.2 miles.
• Arch compression band: Locks the sock in place without a single grip node.
• Targeted cushioning: Heel and forefoot, where every stride lands.
• Anti blister construction: Stops the friction before it starts.
• All distance comfort: Soft from the first mile to the finish line.
