Lake MXZ304 Winter Cycling Boot – Full-Grain Leather, Thinsulate Insulation, Regular & Wide - Black

As a dedicated winter rider who pedals up frozen streams and across snowy singletrack, you know how important it is to have warm footwear that protects your feet. Lake was one of the first companies to make a dedicated winter cycling boot, and the new MXZ304 is their best one yet. A larger BOA dial is moved to the front of the tongue, making it easier to use with winter gloves and providing a more even tension across the top of your foot. Otherwise the construction remains similar the previous model, consisting of Pittards leather that recreates the shape of your foot for optimal comfort, and a heavy-duty Vibram outsole that provides maximum traction both on and off the bike. Plus, they're filled with lightweight Thinsulate insulation, keeping your toes warm when you're out in the snowy woods for hours at a time.

• True winter‑specific boot: Built on Lake’s Winter Last with a high‑volume shape that traps warm air—the best natural insulator—for real cold‑weather riding comfort.
• Durable full‑grain leather upper: Water‑resistant leather with abrasion‑ and water‑resistant protection panels and an adjustable over‑flap that helps keep snow and debris off the top of the foot.
• Warm, regulated interior: Temperature‑management lining plus Thinsulate insulation work together to maintain a consistent foot temperature and move moisture away so feet stay warm and dry.
• Insulated, grippy outsole: Heavy‑duty outsole on a comfortable, stiff nylon midsole with durable rubber tread for sure footing; includes Thermosal Winter Insole—a 5‑layer felt/aluminum/air‑bubble package—for extra under‑foot insulation and a 50/50 on‑bike/off‑bike sole rating.
• Glove‑friendly closure: Tongue‑mounted BOA Fit System M4 dial excels in ice and dirt for micro‑adjustable fit with gloves on; Click‑Fit quick release makes entry and exit easier, and the cushioned over‑mold dial with bayonet‑mount cartridge adds durability.
