Anybody wearing these at the moment? If so, how are they? I've been using Speedcross for a while now because my Achilles has been giving me a bit of grief and my Inov8's are just a wee bit flat for every day running. Personally, my only gripe with the Speedcross shoes is that they could do with being a tad lighter and a bit more breathable. I prefer to run without socks.
