Brooks cadence is very light weight and is so far the best shoe Iv ever worn,I went on a 20 mile run in them today and not even one hotspot (usually get blisters within 4 miles) and zero knee or hip pain. I have never felt so good while running and was 4 mins faster than usual over the same distance. I usually over pronate but land neutral running in these despite the fact that they have less support than most 'neutral' shoes. I dont know why these are only sold in a small selection of stores, my bf would like to try them but there doesnt appear to be a stockist in the whole of the midlands area. I got mine from the moorgate runners need store but they unfortunately did not have the pure grit which I am now interested in seeing as I am getting on so well with the cadence. I have had them for about 2 weeks and have done a few 6 mile runs and now a 20 mile.I used to run in a saucony stability shoe then newton issacs.
