Why do I like this shoe so much? This shoe has enabled me to walk further and at a faster pace without getting sore feet as had happened with a couple of other major brands. I have some hilly sidewalks in my neighborhood and I usually walk fast, about 3 miles a day. The padding is thick enough to adequately cushion while not so thick that it interferes with feeling enough of the surface you are walking on. I credit the Nimbus with helping me stick to a 3 year regimen because my feet don't hurt anymore when I exercise. I wear a 9 1/2W dress shoe but need a size 10W in this shoe. Asics makes this shoe in an extra-wide (EEEE) in some styles, however the EE wide fits my wide forefoot and moderately high instep without being too wide on my more regular sized heel. My wife takes a 7 1/2N in other brands but needs an 8N in the Nimbus. We both started with the model 16 and own several of their other models through the 22. I preferred a thinner sole shoe when I was younger and thinner but these are more compatible with our 60's lifestyle now. My wife is thin and petite and I'm slightly overweight yet the Nimbus works great for both of us. These shoes aren't cheap but they last a long time and feel so good on my feet. I hope that they maintain high quality material standards and consistent sizing so that my wife and I can continue to enjoy them and have confidence in the Gel-Nimbus when it's time to replace. Asics, please don't mess with the toe-box. We both agree, the 16s and 22s were the best of the models we have owned. Just our personal opinion. Others were really good, but those were remarkable. Kudos! Continual process and product improvement enables loyal customers so please don't ever take the cheap route as some companies have. If you like Brooks or Solomon shoes but put on a few pounds, give your feet a break and try these out to get back in the game.
