Imported Nylon sole DESIGNED FOR PELOTON BIKE & BIKE+ – Peloton shoes were designed so that you can get the ideal Peloton workout experience. They include delta-compatible bike cleats that allow you to quickly clip in and out of your Peloton Bike or Bike+, so you won’t waste any time getting started. Tools for cleat installation included. ADJUSTABLE & SECURE FIT – Peloton shoes feature a quick ratchet clip and hook and loop straps that are adjustable so you can get the perfect fit. COMFORTABLE & BREATHABLE – Mesh vents can be found on the base of Peloton shoes so your feet can breathe comfortably throughout your ride. RIDE LONGER DURING CLASS – Stiff sole allows for direct and optimal power transfer without any discomfort allowing you to ride longer class after class. COMPATIBILITY – Peloton shoes were designed to work best with Peloton Bike and Bike+ so that you can get the ideal Peloton workout experience. But they will work with other stationary bikes that require delta-compatible cleats to clip in. FIT – Peloton shoes have a narrow to normal fit. If you fall between sizes or have a wider foot, we recommend sizing up. Typically, cycling shoes should fit similarly to running sneakers—space for your toes to wiggle and complete arch support.
