I recently bought a pair, purely for lying about the house and going to the gym mind. They were a pair of Lonsdale ones. Buying sportswear from a highstreet fashion store seems like a bit of a contradiction to me, a bit like buying your chinos from JJB. (Which some people do actually do!)
That said, those look fine. I tend to avoid ones with a cuff at the bottom, it's not a good look for me.
