I just tried on Purcells and then ordered them from Zappos (the store I went to didn't have white canvas, so I'm not an unscrupulous jerk). After some deliberation on whether I wanted to get a custom pair (I especially liked the top ones and they would have looked better in person):
I decided to just get the plain classic all white with navy smile for $55. I usually wear an 11 in most sneakers and a 10.5 in Purcells was perfect.
BTW, they are much more substantial inside than Chucks or the old USA Purcells - they have a removable insole and padded tongue and were really comfy walking around the store. When I get the chance to play badminton in them, I'll be sure to report back.
