The Butora Sensa Pro is a performance slipper for bouldering, sport climbing, and indoor climbing. Elongated patches of toe rubber across the forefoot provide a large surface area for toe-hooking, making the Sensa Pro perfect for technical, overhanging boulder problems. The medium stiffness midsole creates an even balance between edging support and smearing ability, whilst the highly asymmetric last provides precision and power through the big toe on tiny footholds. The NeoFriction Fuse sole is Butora's proprietary soft rubber compound and provides grip and sensitivity on hard, technical climbs.
But says that street shoe size works well with the Sensa Pro.
