text: These shoes are much better than the prior two versions. I was disappointed and ended up not really using the 15s and 16s. The 17s are very comfortable. I switch between more minimalist shoes and stability shoes like the Gel Nimbus to keep my knees from barking at me. The Gel-Nimbus permits me to run longer distances, more often. Not a great sprinting or race shoe for me, but for training runs, they are great.
