I have achilles tendonitus and these trainers are recommended. I've been looking online but all the sites that sell them that come up seem dodgy. I've checked on trustpilot and it seems that I am right to be suspicious. Where do people order trainers from these days? I bought my last couple of pairs from John Lewis but they don't have the exact ones that I want. Could it be because they are an old model? Would the 25 or 26 be the same?
