I'm looking at getting a new pair of shoes for trail running/hiking. I have a pair of inov-8 x-talon 212a and f-lite 230s, and I like both of them, but I am looking for something with a bit more cushion (for heel-striking when walking), a roomier toe-box, and more toe-protection on top. Durable would be nice also, I don't care about looking trashy, just the shoes still working after 500+ miles.
I'm considering these 3 shoes, all have a 'three arrow' midsole (vs the 2 arrow of the 212s and 230s) and inov-8's comfort last.
Roclite 295
flyroc 310
roclite 315
To anyone who has used some of these, how large is the difference between 2 and 3 arrow midsoles, and how large between the performance and comfort lasts? I think I'm also going to size up.
anything else, other brands, I should consider?
