The design and quality of manufacturing were superior to anything else I had seen. There are sliders in all the right places as well. I REALLY wanted these to work for me, but sadly, one foot was just too tight (fat/wide/whatever), and I couldn't justify spending another $45 on a stretcher in the hopes it would make it good enough. They are wider than the Alpinestars, and Tourmaster wide boots I tried. Ended up with AXO Aragon boots, which are kinda funky, but fit.
Boots fit true to size at least in 13's. Am able to tighten them up on my foot with the cable lace system, so the foot doesn't move inside the boot and enables crisp shifts. Just got them so don't know the durability. They seem expensive for short boots, but my cheaper boots started falling apart right away. I like them a lot.
Hard to rate a pair of boots that you can't even get on your feet.
I thought these boots were poorly engineered. I could not get my feet into them. The gizmos that tighten them up are made of cheap plastic, and were so hard to open I thought I would break them. I had to send them back for a refund because they are no good if you can't wear them, and I knew those plastic fasteners would eventually break. At $350 they are way too expensive for what they really are. Can't say anything about durability, never wore them.
Have only wore them half a dozen times so far, very happy with them. Went a size larger than I usually wear because I have a wide foot and they fit like a glove. Look great and no leaks. They are a little warm but all boots are to me.
Boots are comfortable in riding position, and I can stand to walk around in them for a bit.
My feet/ankles definitely feel protected, but I hope not to test that any time soon.
I haven't done any very hot weather riding, but the boots seem to still get some airflow and keep my feet comfortable.
Walking the bike around is a bit trickier, and it's slightly harder to tip-toe the bike because of the extra ankle support
