This is my second pair of K-Swiss Tubes, and I also bought a men's pair for my boyfriend.  They are very comfortable, well-cushioned, and they've held up very well for long distance running.  I'd bought a pair of Reebok Zigs, and I liked the fit and feel, but the zigs on the bottoms picked up rocks continually!  The K-Swiss tubes afforded the cushiony soles without picking up gravel.  These are also the first running shoes that did not give me blisters running a marathon.  They run true to size.
