I like New Balance. They come in a variety of widths, and mine do indeed have a boxier toe. I got mine at a discount Lady Footlocker that has last season's shoes. I got them for 70% off.

I like to browse Zappos.com to get a feel for what kind of shoes are out there. They have a pretty good return policy, too. I usually get nervous about buying shoes online though, because I never know what size I'm going to be in a particular brand.
