Not sure why they put an L or R on the sock but figured Id try it and after stretching them out by hand, putting them on and then switched them and I honestly couldn't tell a difference. Fit size 10 but would be surprised if it fit an 11 or 12 though I may be wrong but it was tough getting them on properly the first time. After several uses and washes it was easier pulling them on even though they remained tight and they washed fine also. Fabric feels good and though tight (not small) I would recommend.
