Why buy new straps if you don't need to! The B-sides take a brunt of the impact for the average rider. If your A-side Velco and hardware are still good, you may just need a new pair of B-sides.
Simple remove strap from pedal (we recommend one at a time to avoid confusions). Swap out B-side, making sure to match up your Left and Right sides accordingly. You can then follow our installation instruction to remount you straps to you pedals.
