Love these running shoes -- even if they're last year's model. Originally was using the Nimbus 11 when I switched from the Nike Vomero's. But then it was difficult to find the Nimbus 11's in my size, so I had to I tried the Nimbus 12's, which were quite a bit more at the time. Now I'm spoiled. I purchased two pair for the price of one of the Nimbus 13's. They should last me a good 6 months of training. Perhaps by that time the price of the Nimbus 13's will have dropped enough to give them a try...??? Oh yeah! The transaction and communications with the vendor were great. Received them within a week as promised. Thanks for the great service!
