I've been using the Asics Nimbus 15 now for a few years. I have had about 6 pairs and have had no problems. I thought I would upgrade to the 16's, but do not like this one as much as the 15. Maybe it's supposed to have different kind of support and I missed something.<br />I don't feel like it has the arch support like the 15h. It doesn't seem to  have has much support. My right  foot on one side starts to get numb after a long run and that never happened with the 16's.<br />Not happy with this shoe...
