●EU Size: 38 – US Size: 6.5-7 Women/5.5-6 Men | Versatility Expert | With a subtle downturn, supportive midsole, and fast break-in time, the Quantix SF blends comfort and performance from gym climbing to outdoor sport routes. ●SF Tension System | This rubber rand wraps the shoe from below, starting from the toe area, to keep your foot in a performance position and ensure your new climbing shoes maintain their shape over time. ●Flexan Dynamic Midsole | The medium-stiff Flexan midsole reduces foot fatigue on long climbs and offers a powerful platform for toeing down on small footholds. ●Vibram XS Grip 2 Rubber | Ideal for any rock type, the XS Grip 2 rubber is both stiff and sticky, giving you the grip you need for steeper walls and overhanging boulders. ●Sizing Advice – Synthetic climbing shoes should fit snugly and will not stretch much over time. An ideal fit should have no dead space out of the box. Use the sizing chart in the product images or description to find your size, then downsize ½ to 2 sizes for premium performance.
