i bail onto them so it doesn't hurt when i fall, without them my doctor says i won't be able to walk proplerley so i thought maybe a good idea to where them. I had the exact same problem for my first 2 years of riding my knees caned all the time so i went doctors and thats what they told me so i wear them now and i feel more confident when riding i try harder things, i where them wherever i ride even on the street because if i do drop on my knees i cant ride for ages
