I wear a size 1.5 in youth or a size 5 in womens. what V-Toe socks should I order?

I wear a women's size 10 shoe. i found v-toe athletic black asin: b01fuov2kc which says it is thicker. do you have the thinner socks in my size?

The title says "4 pairs", the description says "3 pairs." So which one is true?

Are the bottoms of the socks anti-slip or textured to grip wooden floors?
