I bought the purple and grey, size 9.5 pair.  I have narrow, long feet and have a hard time finding shoes to wear, especially since I don't wear leather or suede.  Just about every shoe I try on is too wide or rubs blisters on my feet, even if it's the right size.

I like these because they are pretty narrow, despite being medium-width.  They're also very light shoes, they're squishy on the inside, they're really comfortable, and they make great walking shoes.  I tried on some Nikes that were similar, but they were too wide and made my already big feet look even bigger.  They also rubbed uncomfortably on the skin right below my ankles.  These don't rub blisters on my feet and didn't take any time to break in.

I used to wear Converse all the time, and I think these are way more comfortable, though I still like Converse.  The only downside is that they are pretty expensive.  I'm happy with them, though, and glad I got them.
