The Lake MX30G Cycling Shoe wraps a slim, race-tuned last around the foot for maximum power transfer on long gravel days. We chose the microfiber upper for a shoe that shrugs off trail debris and knocks, or the mesh upper when heat and water crossings call for fast drainage and steady airflow. A 100% carbon fiber sole with TPU lugs keeps the platform stiff underfoot while still gripping loose ground off the bike. What Our Gearhead(R) Experts Are Saying:"I've cranked down the BOA Fit System mid-climb without losing a pedal stroke, and the fit tightened evenly instead of pinching one spot."
