I have multiple issues w/ boot-fit; large calves [so taller boots are out], wide feet [12EE], and high arches/insteps which means I often can't even get my flippers into the damn things. Last year on a close-out deal [the shop - not the boot] I bought a pair of Alpinestar Tech2s, which look like a short MX boot w/ a buckle closure, ...bought 'em just because they fit, wasn't convinced yet, but the price was right. Turns out I really like them!
They're very comfy, easy on & off, not overly hot in high temps [a worry going in], and after riding through a coupla good deluges in WY & NB [including lotsa of 18whlr back-wash] I can vouch for them being waterproof! The break-in was pretty nominal & wasn't the problem I'd thought it might be. I've got about 8K on them and am thinking I'll score another pair while they're still around. Shift technique took a few tries to refine but came easily enuf, though the boot is fairly stiff so it wears your lever-rubber a tad. I feel they'll give your ankle fine support if asked to, I'm figure they've already saved me a potential sprain when I did a slow fully-loaded tip-over on uneven tarmac.
This Summer on the road I checked a few shops along the way to see a few items hands-on that I hadn't found around home, and crossed a couple of other boots that afford me a fit. My Alpinestars BTW are a size12, ...I also found a size47 Diadora "Express", and a size12 TourMaster "Response" would accomodate my clodhoppers.
