I bought this shoe from my LBS because I read a review here about how the shoe size runs small, and I didn't want to mess around with the possibility of a mail order return. Here's my what I found. I take size 9 1/2 with Merells and Chacos, and a size 10 in Rockports. With these shoes size 10 fits perfectly. So I think the sizing is about right - at least for a medium-sized foot. Your mileage may vary.

Something I learned from my LBS is these shoes can be resoled by Five Ten for a nominal charge. That's almost unheard of in this disposable world! Nice to know they offer this service. The shoes do seem very well-constructed so it may well be the soles could wear out before the rest of the shoe.

I find these shoes very comfortable for pedaling. I think the ventilation is actually pretty good (I can feel air getting through the top of the shoe and cooling my foot) and so far I haven't managed to sweat these things out even on a fairly strenuous and long ride. I am more concerned about how warm they will be when the weather gets cold. Also, the sole is pretty stiff, which is what you want for bike riding. I think the sticky sole feature is dramatically overstated by most reviewers. I find these stick like a pair of tennis shoes, which is not bad (and way better than Vibram-soled hiking shoes).

If I am going to do much walking or standing though, I don't find them to be very comfortable. There is not much resiliency in the sole or insert, and foot support is pretty poor for walking. If I am going to be walking or hiking much, I bring a pair of shoes for that (the joys of panniers). Again, your mileage may vary, I have lots of foot problems so I am very picky.

I think these shoes look pretty good in black/grey and work with most casual wear.

Addendum 8/10/2012: Lately I've been riding my bike to the gym and it turns out these shoes are great workout shoes!
