A super sticky approach shoe designed for high performance protection.


* Required Fields

We tweaked the designs of proven technology from years past to produce the Boulder X. Additional padding underfoot for long approaches and uber sticky rubber add deluxe comfort and performance. The Vibram® Idro-Grip compound stays sticky on every type of rock even when wet. The all-leather upper and sticky rubber toe rands offer durable protection. Ideal protection and performance built for the rigors and abuse of the mountains.
• High-cushion LaSpEVA layer above the 2mm polypropylene insole cushions the foot on long approaches
