Serfas Krypton Women's Titanium/BLK 39

The Serfas Krypton Women's MTB Shoes in the Titanium/Black colourway (Size 39 EU) are performance-oriented mountain bike shoes designed to offer premium, race-level features at an accessible price point. They blend high power transfer with a more forgiving fit than traditional cross-country race shoes.

Key Specifications & Performance

• Sole Construction: Engineered with an ultra-stiff Carbon Plank sole to maximize pedaling efficiency by eliminating sole flex, ensuring all your power goes straight into the pedals.
• Fit & Geometry: Built with a Women’s Specific Design (WSD) featuring a narrower heel cup alongside a generous Wide Toe Box to prevent hot spots and toe numbness on long trail rides.
• Closure System: Utilizes a quick-adjust Easy Release Single Button Buckle system paired with hook-and-loop straps for secure, mid-ride adjustments.
• Upper Material: Crafted from a lightweight Syn-Tech+ microfibre upper with high-efficiency ventilation ports to keep your feet cool in warm weather.
• Cleat Compatibility: Standard 2-bolt SPD style (compatible with Shimano SPD, Time, and Crankbrothers mountain bike cleat systems).
• Weight: Highly competitive at approximately 375 to 390 grams per shoe.

Sizing Breakdown (EU 39)

An EU Size 39 in Serfas women's footwear generally maps directly to a US Women's Size 7.5 to 8. Thanks to the wider toe box design, these shoes are an excellent choice if you prefer wearing thicker cycling socks or have a slightly wider forefoot.
