Puma 7.5's are about the equivalent of Nike and Merrell 7.0, so you may wish to increase your typical size by 1/2. These cross-training shoes are comfortable, with nice ankle cushioning and a slightly wide base for good stability. They're well aerated so are best for summer use in dry conditions. The distance from sole to tongue is slightly less than I've found from comparable shoes of other manufacturers so it fits tightly on the foot in that dimension. I found it best to use thin socks with these rather form-fitting shoes as a result. The laces hold a tie well and don't loosen over the course of the day. I tend to prefer shoes that I can wear to work without having to change, so the black/red pattern is less than ideal. However, for running in traffic, the visibility is high with the bright red portions of the shoe, so you may find that point an attraction. Overall, I find these shoes comfortable and appropriate for their intended purpose.
