• i think they are USA sizing. STP made a mistake on the men's small sizing. should be (look on amazon) , they have small as 1.5-4.5 Men, medium 4.5-7.5 Men. i do not know how STP converted to women's sizing, i could not find women's sizing on the internet for Chainsen, but i can see why you would be suspicious.
    men's should be as follows (from amazon) Sizing - S: 1.5-4.5, M: 4.5-7.5, L:7.5-10.5, XL: 10.5-13.5, XXL: 14+
