Note: ProtecShin guards are a balance - they are slim, easy to wear when you feel like trying some tricks or want to send it, and take up almost no space in your pack. Made of thermoplastic polyurethane, they are ideal for absorbing impacts and will* stop pedal pins from puncturing skin. However, you may still experience bruising and associated pain from the impact, simply because they are designed to be thin and minimal. Additionally, if you ride with low socks, then these will not work, as the bottom half will be unsecured. Please consider these variables when deciding on ProtecShin guards!
*While the guard itself withstands puncture from pedal pins, there is of course still the assumed risk that the pedal may find its way to a part of the leg that is not covered. As always, ride within your own capabilities and acceptable risk level!
