These shoes are great...I owned a pair that I wore out, and thus purchased another one.  One negative though...the green plastic on the sole seems to come away from the shoe, however this can just be super glued with ease.

Really like the laces.

Also...I washed these like the directions said...straight in the washing machine and they came out great.

Personally...I never used these for marathon running, just walking around the office, home and the neighbourhood.

Definately recommend this shoe to a friend and I am a repeat customer
