I have been hiking about three to four times a week for the last year or so, averaging five miles or about 2 hours of hiking for me. I mostly wore my Merrell Chameleon Stretch's (I'm into my third pair), and I love thm for their traction, nimbleness and flexibility. However I've recently suffered a stress fracture in one of my left metatarsals. Of all my shoes and boots, the Merrells were the worst in terms of aggravating the injury. (actually the worst culprit was/is me for not staying off my feet). The only shoe that I could painlessly wear and continue to hike is the Patagonia Drifter GTX. It has a high volume toe/ijnstep box, a stiff shank, and gives good support. The one drawback is that for some reason they make me more prone to turn my right ankle out. I have six pairs of hikers and they were the most painless.
I recently got a pair of Keen Voyageur Mid hikers that so far vae been awesome! great traction, wide toe box, NO toes jamming on descents, great anke support and only minimal pain post hike at my injury site. I hope this helps, I know I answered your very specific issue with my very specific issue but I've been drinking

Oh and I would also suggest one of two things;
1. get a pair of Superfeet insoles and try them on your current favorite hikers to see if that helps.
2. Get some shock cord to replace your laces, still tie them fairly tight or use cord locks to adjust on the fly. that should provide enough stability and support but get you a little room to swell.
