Bike shoes



I recently finished Maddie's custom biking shoes. Here are some specs:
  • three layers of 5.8 oz carbon over five layers of 6 oz fiberglass form the base
  • West system epoxy
  • PVC upper with carbon fiber look
  • two velcro straps
  • a tongue but no eyelets or laces, I am hoping that the straps will be enough
  • 1.5 mm thick neoprene liner with nylon cover
  • extra evalite padding around cuff
  • each shoe weighs in at 247 grams with the SPD cleat attached
Maddie hasn't tested the shoes on a bike yet. Actually, she doesn't have a road or track bike, but she does spin classes at the YMCA a few times a week. Bike shoes, in my opinion, are easier to make than speed boots, or maybe I am just getting better at these projects. The photos look good but the carbon work is full of wrinkles that are mostly covered over. I think that I used too much vacuum and with the fiberglass layers the tendency to wrinkle was increased - another lesson learned.
