Engineered for real winter riding, the Lake MXZ21 combines race‑level pedaling efficiency with the protection you need when temperatures drop. A carbon competition midsole pairs with Lake's Mountain Competition real‑rubber outsole to deliver crisp power transfer on the bike and confident traction off the bike in slick, mixed conditions. Up top, a windproof, highly water‑resistant upper blends soft‑shell fabric and durable microfiber with a wicking liner and seam‑taped membrane barrier. It's treated with a DWR coating to help prevent water absorption—simply reapply with a common DWR spray as needed to maintain performance over a long, wet season. Fit is simple and secure thanks to speed‑lace closure and supportive hook‑and‑loop straps. Built on Lake's MX Competition Last, the MXZ21 balances a secure heel with extra toe‑box room for comfort under load. For use with thicker winter socks, Lake recommends sizing 1–1.5 sizes up from your typical Lake fit. Rated down to 25°F / −4°C, this is the winter shoe you'll actually look forward to wearing.
