Sorry for the late response. I haven't tried CA so I won't be able to comment on them. I am an over pronator too. The best ones I have found to help me with this issue are either the Asics gel speed menace or any of the nike spikes. You will find really good deals for the older nike spikes models like the 2010 one. I tried adidas last year series but didn't like them at all as my foot is a bit wide so didn't use them much, but they weren't that stable. But if you get the opportunity do check out their new one called vector( sorry if the name is not right), a lot of players are using it. In UK and Australia there are loads of companies popping up which can spike up any trainer you want. So have a look around, wear them yourself and then decide. I hope I was helpful enough!
