I have been a loyal Asics runner and thought I'd try these. One of my favorite first pair of Asics were the Cumulus 12 (?). I did some research and thought I'd supplement my Nimbus 17's with these Cumulus 16's. I found them hard in the body, with little give/cushion at all. It felt like I was wearing hard, patent or fitted shoes. An old injury in my knee resurfaced after mile 3 on my 1st run with these. Whatever happened from my first pair of Cumulus' and these sure didn't improve for this gal. If it hadn't been muddy, I would return them and stick with the Nimbus.
