When I first started working out, I quickly realized that my running shoes were not going to cut it for activities like aerobics and Zumba. With my wide feet, I had trouble finding a good pair of cross trainers UNTIL I found Rykas. Currently wearing Assist XTs and they are fantastic!! Excellent support, plenty of room in the front, and so very comfortable.
Make sure you try on before you buy. I had read on other reviews that you normally have to buy 1/2 to 1 size LARGER than your regular shoe size, and that was true for me as well! (I wear 8/12 to 9 and my Rykas are 9-1/2)
