Castiron Grip
The Wall Demands Precision.
It only responds to how well you move. Every crimp, every smear, every heel hook — your connection to the rock starts at your feet. The wrong shoe doesn't just cost you comfort. It costs you the send.
Castiron Grip — formerly known as Rock Planet — is built for climbers who take that seriously. Beginners finding their first foothold, youth athletes building technique, performance climbers pushing their limit — footwear engineered for the wall without compromising the standard of the street. Precision rubber where it counts. Feel and sensitivity where you need it. A fit that works from the gym to the crag.
Same shoes. Same rubber. Same performance. New name, new standard.
The Full Lineup

N23 — Precision Edge Climbing Shoe
The N23 is built for climbers who live on the edge — literally. Neutral profile, lace-up closure for a precise fit, and a stiff midsole that transfers power directly to the foothold.

HUG — Kids Beginner Climbing Shoe
The HUG is the first climbing shoe built around how kids actually move.
