Nike Thermal Legwarmer

I ordered a set of leg and arm warmers, sizes L/XL and L respectively (the arm warmers were not Nike). I tried the what I thought were arm warmers and they fit my arms ok, a little small, but when I tried the leg warmers, well they were too tight. I checked the order and the leg warmers were Nike size L/XL... I cannot get them over my size 8 foot. they weigh 38 grams. 14 inches long, 5 inches across the top and 3.5 at the bottom. the Arm warmers are 98 grams 20 inches x 6.5 x 3.5. Some how I thought the one size larger leg warmer would be Larger than arm warmers. My legs are larger than my arms. They are a little small for arm warmers and not as warm as the other brand. I think I will match the other brand for my replacement leg warmers and keep these for not so cold arm warmers. Could these be for little girls dancer legwarmers? I do not see anything that would indicate if these are adult or child sizes.

The product was exactly what I wanted to help keep my calf muscles warm. Great fit.Note--I purchased the large/x-large size. My calf muscles are what I consider average for a guy--not huge but not skinny. The small/medium would probably fit slim female calfs. If you have very large calf muscles, I'm not sure what size you should purchase.
