The 2-piece outsole features RS 3.5mm rubber combined with a fish hook midsole in the forefoot. This provides a direct feel as if gripping the foothold with your toes, and delivers otherworldly friction during serious smearing. • The inside edge of the forefoot outsole is extended to improve smearing performance on the inside edge. • RH 3.5mm rubber and a high-rigidity midsole are used in the heel, providing all-around support for various heel hook shapes, while also fitting the heel shape securely and exhibiting excellent tracking. • A VD toe rubber patch that largely covers the forefoot is employed, supporting delicate and serious toe hooks. • A slingshot that firmly lifts the arch, along with a simple and highly durable single Velcro strap and split tongue, provides a smooth feel when putting on the shoe while also delivering an excellent fit.
