Ocun Diamond S Climbing Shoes - Black - EU 38.5

Push your limits on steep boulders and technical sport routes with the Ocun Diamond S, a high-performance climbing shoe built for precision and power. The aggressive downturn and highly asymmetric last position your foot for maximum force transfer on overhangs and micro-edges, while the Vibram XS Grip sole delivers reliable friction on smears and tiny footholds. A single Velcro strap and slipper design allow quick on-off between burns, making these shoes ideal for climbers who demand both performance and convenience. The black microfiber synthetic upper offers a comfortable, unlined fit that molds to your foot without excessive stretch, and the tensioned rand secures the heel for confident heel hooks. Whether you're projecting your hardest boulder or clipping bolts on a steep wall, the Diamond S gives you the precision and support to climb at your best.

Good to know

For the best fit, many climbers downsize 1-2 EU sizes from their street shoe size. The synthetic upper will stretch minimally, so choose a snug but not painful fit. The tensioned heel rand and pointed toe box are optimized for hooking and pocket pulling. To prolong the life of the Vibram sole, avoid walking on abrasive surfaces and store the shoes away from direct heat.
