Didn't really think to ask the bloke in the shop when I bought my new trainers today.
Wen t in with my 1150's just to show him the wear on the sole. He asked me how I had got on with them, fine I said, no problems at all.
So he recommended I stay with the same make and trainer as it would be silly to try something new if the 1150's had served me well. However he then said that asics had upgraded the 1150' to 1160 now, so I came away with a pair of 1160's for £70
Going to break them in over the next few weeks to see how I get on with them. Just a shame they are going to get dirty, they look so nice right now
