I'd be interested to know how you get on with the new 315s. I loved the orange and grey ones and went through three pairs so when they changed to the blue and grey ones I just assumed they'd be the same and got a pair of them. The fit was definitely different and they gave me horrible heel blisters despite the fact that I bought the same size. I haven't dared to buy a pair again and went for the Roclite 268s (womens) which are comfy but not as good as the original orange and grey 315s and the uppers got holes in them in no time at all.
