Unparallel Sirius LV Climbing Shoes - Low Volume Aggressive Lace Shoe

The Unparallel Sirius LV climbing shoe is a low-volume, aggressive lace-up for demanding projects on steep and technical terrain. Full RS rubber and a precision offset lacing system deliver exceptional friction and sensitivity in a fit made for narrower feet.

The low-volume last cuts dead space for maximum control. Underfoot, the 3.5mm RS outsole is a softer compound that gives superior friction, excellent smearing and grip on micro-features, while the medium-stiffness midsole keeps enough support for edging. Offset lacing lets you adjust the fit precisely across the foot and increases rubber coverage over the toe for toe hooks. At around 340g a pair with a lined synthetic, vegan-friendly upper, it's a genuinely lightweight performance build. Choose it when you want friction and precision at the highest level in a narrow fit.
