I have several pairs of these trainers. The grey ones are the only ones with a fleece liner, but it's only around the sides & top, not on the inner sole which is a shame. I visited a store yesterday & saw these are now in the sale, so a bargain.The only problem with these trainers is they do stretch a bit & loosen off. The actual sizing remains ok but the top & sides loosen slightly, so I popped in a pair of inner soles & it corrects the looseness. So I'd say buy your true size but be prepared to add inner soles after a few wears.
