I have wide feet...not so much my heels (they are actually a hair on the narrow side), but definitely the front half. Think of a duck's feet. If I had webbed toes I'd be a freaky-good swimmer.

I have found that after about 2 hours the outside of my feet start to hurt--particularly on my larger/wider foot. The area is generally right around the peroneal tendon. Here you can see photos of my feet (I recently sprained my left ankle and my left ankle and foot are pretty swollen, but you can see how paddle-like both of my feet are):

My shoes are Sidi Dominator 5s, size 40 (I typically wear from a 7.5-8.5 wides when I can find them, depending upon manufacturer...at least for running shoes). Length is good, but I have always thought they were a hair narrow...though I know they aren't supposed to fit like running shoes. I have the 2 velcro straps across the forefoot about as loose as they can go and still stay put. The upper doesn't feel terrible, but what seems to be the issue is the plastic sole piece. It feels like the outer edge is cutting along the underside of the lateral edges of my feet.

After today's 71 miler this area is actually pretty red and swollen on my right foot--even on the top of my foot.

I otherwise like the shoe and the length is good. I'm thinking I probably should have gone with the men's version, though, as I wear a D width in running shoes and D is a men's medium (women's mediums are Bs) and am thinking I may go ahead and order a pair of the same shoe in a men's model (assuming the heel fit wouldn't be too loose). Or maybe look at a different brand entirely. If I did that, can anyone recommend a shoe that would be similar to a size 40 Sidi Dominator, only wider through the forefoot?

Thanks, ladies!
