Use them for running, really well made. I love Sugoi! First I bought the Piston compression tights which were great (minus the letters falling off after several washings - of well..) and went to buy another pair. Unfortunatelly my size (S) was gone. Therefore I have decided to give this RSR tights a try but bought XS which was a very good decision because these are larger than Piston. They are not really compression tights so with those, go for size smaller. All in all, very good buy - I recommend them!
