GRPZ Workout PRO
Built for the lift. Designed for the last rep.
GRPZ started with athletes losing grip inside their shoes. In the gym you might be in a flat trainer, or barefoot on a mat, or on rubber matting in socks. The surface keeps changing and the problem does not.
Under load your foot slides, your plant point moves, and the rep that follows is a compensation for the one before.
So we built one sock that holds in all of it.
- Interior & Exterior Sole Grip: Locks your foot and your sock at the same time.
- Ankle length: Minimal profile, no bulk inside a low cut trainer.
- Compression arch band: Arch stability through heavy and high rep work.
- Cushioned sole: Impact absorption on gym floors and rubber matting.
- Trainer or barefoot: Same fixed base either way.
