I've run in GTS 12s and I use the pure cadence 2 for races. I'm currently weighing up running my next marathon in the cadence. No problems after a half, I'm carrying 13 stone plus round as well and felt I needed the extra support in the GTS but I'm beginning to think otherwise. I love the Cadence 2. Another endorsement for you.
Pure cadence 2 are a winner for me. I have a noticeable bunion on my right foot so was wondering how the split toe box 'thing' would impact and it hasn't. They are so comfortable and I'm lumping 13 stone plus round over half marathons.
Cheers Ben. Hence my question about mileage. I bought some on eBay recently described as nearly new and that's how they felt after id bought. Trusted the answer I got re mileage. 35 quid. Bargain (in my opinion). Of course that won't happen all the time. Buyer beware.
