not wearing out, in fact my dexters sst5's were 6 years old, but the sole kept ripping up on the trail foot, so i sent them back, guess what Dexter replaced them, sent me a brand new pair of 5's last night.
for the record they looked very good condtion wise when i sent them back. I wlll wait to pass judgement on the tour ultras i am wearing now, they seem to wear pretty good, have had them in service since the first of april so not really enough time to get a good feel for them yet
