Peter - I see that shoefitr now lists both old and new versions of the Roclite 295. That is recent, as the last time I looked they only had the old model. I've not been able to do a direct comparison between old and new Roclite 295s as the software thinks they are the same. However doing a three-way comparison with the TrailRoc 245, shoefitr now suggests going 1/2 size larger in the new model than the old. That wasn't enough for me widthwise, and 1 size larger felt too long. For reference I wear 10.5 (all sizes US) in the old Roclite 295, 11 in the Roclite 312GTX and 11 in the Trailroc 245. shoefitr suggested I should wear the new Roclite 295 in 11.5 and strangely the old Roclite 295 in 11 based on my Trailroc 245 sizing.
In contrast, Zappos replaced the picture of the Roclite 295 to show the new model, but retained all the reviews and fit feedback for the old model.
The Roclite 285 has been replaced by the Roclite 243 (which I see they now say has a 'Precision' fit - so confusing). The 285 has the Performance last, which is narrower than the 295 (either model). I believe the Roclite 286GTX also has the Performance last. I'm told the Terrafly line has been updated, although the 303 looks the same as last year. I can't comment on the Terrocs as I've never found any locally.
The Trailroc line was introduced last year, along with the Anatomic last. I wanted to get a pair of 255s (6mm drop) but couldn't find them in stock so settled on the 245s (3mm drop). After wearing the 245s for 3-4 months I tried a pair of 255s through Zappos and sent them back. Between the amount of cushioning around the heel, and the plastic met-cradle on the outside, the heel felt much narrower and was decidedly uncomfortable. I recently acquired a second pair of 245s and they fit as the first pair did. Initially I was concerned about the 3mm drop, but my left knee and ankle are much happier than they were in any other shoes I've worn. These are my go-to shoes outside of winter and mud season.
Take a look at the combined footbed and drop measurements for each shoe to get an idea of how much cushion exists. I started with a 6mm footbed with 6mm drop, then moved to 6mm footbed with 3mm drop. The latter's sole is much more flexible but the Trailroc 245 has some form of plate in the sole and that helps protect against sharp rocks. There's less roll in my ankle on the lower drop shoes, but that also may be a function of the smaller lugs on the Trailrocs than on the Roclites.
