Is this the answer everyone’s been looking for? Could be. Retrofitz makes these SPD kits, allowing you to cut up your sneakers of choice and add a cleat-mount. While they don’t sell the part kit outside of Santa Cruz, you can buy some ready-to-go conversions at their site. So is this the answer? Maybe, if that’s what you were looking for. But I din’t think the solution is as simple as this. Not unless you add a high-density nylon flank to the insole. But it’s a start.
