You can put pvc/vinyl (electrical) tape on the orange part of the foot bindings. Just cut a piece slightly larger than the exposed orange foam, stick it on and tuck the ends under the black rubber part. It sticks surprisingly well and will perfectly match your springs
You can use the same idea for the calf-pad, but you may want to use the larger size of tape so there are fewer seams. If the ends of the tape are tucked underneath the backing, it should hold up well, and it doesn't look bad either
