Volleyball LR6 volleyball knee pads

Mizuno volleyball knee pads size M. My daughter has these in white and they are the only brand she likes. We tried every brand out there. She likes the thickness of these - not too thick and not too thin, and she likes how they feel. I bought them in black because when we go to multi-day tournaments I wanted to have different pairs for each day since the white ones get dirty after one use, but she is refusing to wear the black ones. She doesn’t think they go with her uniform or white shoes. These are brand new without tags. Never used. In terms of sizing, I measured my daughter’s legs where the knee pads go, and it is 10.5” on the bottom and 12” on top. My daughter is a skinny 11 yr old, 58.5” tall, 76 lbs. bought for $29.99.
