great sock i use them every day now as i am on my feet all day they really do make massive difference i can not fault them in any way shape or form so pleased i got from this seller . i work in the security sector so on my feet all day long i wanted something that would really help me, i have now found the right sock your feet can breath i do not get the throbbing aching feet at the end of my shift no more, even after many washes they still work feel fresh my feet do not hurt like they use to do moving on different surfaces the cushioning in the sock work so well 100% happy chappy 5 star from me thank you
