Rubber DESIGNED FOR ALL-DAY COMFORT: Built with Engineered Knit Technology, these climbing shoes provide breathable stretch and support. Ideal for long gym sessions, cragging, or multi-pitch routes where comfort is key. DURABLE RUBBER OUTSOLE: Features a 4.3mm rubber sole that balances grip and longevity. Engineered for consistent performance on plastic holds and real rock surfaces alike. SECURE & CUSTOMIZABLE FIT: Equipped with two hook-and-loop straps that allow fast on/off and easy adjustments. Ensures a snug, secure fit that adapts to your climbing style. STABLE & SUPPORTIVE: Soft flex midsole delivers reliable edging support while maintaining sensitivity for smearing and technical footwork. Built for both beginners and experienced climbers. BREATHABLE & LIGHTWEIGHT: Engineered upper provides ventilation to keep feet cooler during long climbs. Lightweight construction minimizes fatigue without sacrificing durability. Whether teching your way up a run-out granite slab or hucking laps on the splitters at Indian Creek, the Aspect is an engineered trad climbing machine. Built with the highest grade European leather upper, the Aspects balance comfort with performance using innovative designs that subtly set it apart. Lace up a pair and you'll notice that the leather upper slightly covers the laces on the outside of the foot-specifically designed for protection during abrasive jamming. The shoe's tongue is made from our Engineered Knit Technology, which adds breathability and comfort. The knit also extends to the outside of the shoe to just under the rand line to offer extra padded protection for foot jams. The lateral stabilizer rands increase precision by keeping your foot from rolling when pressure is applied to the outside or inside edges. The Aspect's stiff and durable rubber is unique in that it's molded-inspired by the way we forge our carabiners-and not cut from one sheet of rubber. This is our engineered solution to optimize our shoe's rubber and rands for weight, consistency and comfort. The Aspect's medium-flex midsole adds support without sacrificing comfort. So next time you're eyeing that trad line, consider the Aspects a part of your rack. Get the whole story here.
