Silicone foot paw socks, fun to play with, it is based my feet and the size is about 10.5 (us size)/ 40-45 (chinese size )and 39-44 (eu size )
I just asked the factory , for now (till the end of feb.2020 ) one of this cost 217 USD and a pair of them cost 360 USD to make , if more then 10 people are buying them then the price will be much lower (from 217/360 USD to about 140 /184 USD ) .
