Great shoe. This is my third version of the Gel Nimbus and after some bugs (versions 18 and 19) ASICS is back in the game. I was a size 16, then a 20 and now a 21. Fits well - not too tight and not too loose. Light and comfortable. A few years ago I had problems with my knees after running on the Autobahn, then the Nimbus was recommended to me and it has been helping me ever since. After thousands of K's, there have been no knee problems since. After reading the Revain product descriptions regarding the reflective materials, I found that this is not the case with other colorways of the same shoe iteration 21. So I traded for this Lite Show version and it delivers. Shoes reflect light with a multicolored rainbow effect. Certainly perceptible in the beams of light from a passing or oncoming car before dawn. That was a big part of my purchasing decision and this Lite Show version is a treat, but not the other colors. I recommend this version for winter running in low light conditions.
