Built using the same super-comfortable, semi-asymmetric last found in their top-selling shoe, Boreal\'s Alpha Climbing Shoe is perfect for beginners who are finding their feet. Their low-tension integrated rand system relieves pressure on your foot, with the durable one-piece construction providing effective support that retains its shape over time. The unlined microfibre upper feels comfortable next to the skin, and they also use Boreal\'s Cushioned Heel System (CHS) which places an EVA shock absorbing insert under the heel to cushion and protect the foot. They provide the ideal blend of edging support and long-lasting friction, all due to the medium stiffness midsole paired with the sticky and durable Zenith Quattro rubber outsole.
