These are some of the best shoes I have ever owned.  On a bicycle, they grip platforms with spikes almost as well as clip in pedals.  They grip my flat platform pedals on my townie too.  The are super comfortable as walk about shoes.  The best thing about these shoes is the depth and insole.  I wear orthopedic inserts, so I usually take the insole out and replace them with my inserts.  Most shoes are not designed for this.  These 5-10s seem like they were made to take orthopedic inserts.  I'm not sure how comfortable they would be otherwise, but I liked these so much I bought a second pair for future use.
