Christ, that's not normal!
someone on here reckons the quality has gone downhill recently, not sure why though.
I've said that. The stitching on them has got a bit inconsistent, I've seen several pairs of F.I.13 S5s with panels stitched asymmetrically, seams on the piss etc, sadly that's coincided with the crazy price rises, the F.I.13 S2s which were about £130 were still the best they've made IMO. The Unos have too much padding and it's in the wrong place I reckon! The stitching on the pads has always been a bit of an issue, I've worn that through on a couple of pairs, and a friend of mine used to do it pretty quickly.
Never seen wear like that though, that's got to be your saddle! I've got 8 year old tights with less wear than that. They do say that damage caused by saddle stitching isn't a warranty issue, but I'd be sending them back if I were you!
