sbd apparel knee sleeve size Small

I bought size small SPD knee sleeves try them on and they didn’t fit. Didn’t feel like going to the hassle to exchange because at the time there was no size up on there website. Never worn, except the one time for me to try them on. IPF approved and USAPL, USPA and IWF compliant with the maximum allowable 30cm length. 7mm neoprene
