I have a option to buy some Race Face Indy knee pads, at a killer price. But I have no way of trying them on first. The Race Face size chart is kind of confusing and I don't really seem to measure up. My leg seems larger then the XL when measured. I contacted Race Face and all they can really say is that they stretch. I don't think my legs are that big. I'm only a 34" waist. Any help?
