As a 17 stone 6'3" plodder of some years standing I have tried just about every 'Big Guy' shoe that there is over the last decade. I know that its horses for courses but I had endured years of those little blisters on my instep from Asics MC+ (now called Koji) and Kayano. In the last year I got a pair of Brooks Addiction and then upgraded to Brooks Beast. They are simply the most comfortable shoes that I have never known, supportive and stable like nothing else. Since I have gone over to these I have upped my mileage and got a whole new enthusiasm for running. What more can I say?? But then I am a few stone heavier than you...
