The MX239 is the latest iteration of our most popular gravel biking shoe, designed for adventure seekers. This updated version of our legendary MX238 Gravel features an integrated tongue on the upper's medial panel for a firmer foot hold, enhancing stability and power transfer. It comes with a new fiberglass-reinforced internal heel counter for improved heel hold and increased spacing between the two BOA dials for better forefoot zone adjustment. This shoe elevates off-road adventure cycling to new levels of comfort, fit, and performance, with modern styling. Paired with the Mountain Race X real rubber sole, it's ready to tackle any challenge. The MX239 Gravel offers a larger toe box and a tighter heel cup compared to the Comfort Plus Last, with slightly more overall volume than our Sport Last, ensuring exceptional security on loose terrain. The shoe provides ample toe box room to prevent binding during inclines or technical sections, offering a more natural foot fit. Fitted with our Lake Competition 100% Carbon Fiber Sole and Mountain Race X real rubber sole, it delivers super-stable off-road cycling performance. With extended toe protection and lug-fitting opportunities, it ensures stability on various technical terrains. This high-performance road cycling shoe offers a choice of Clarino Microfiber or Recycled Leather uppers with Mesh and Helcor Abrasion resistant leather panels and Outlast heel lining. Committed to sustainability, our shoes are designed for longevity and repairability. The MX239 Gravel features a BOA Fit System with a Li2 Push/Pull dial, offering precise, micro-adjustable fit in both directions and resisting abrasion. Our dual BOA fit system, combined with pattern work, world-class shoe Last, and superior upper materials, ensures Lake shoes are renowned for their exceptional fit and comfort.
