I only have one pair of running shoes (adidas boston) but my feet are suffering a bit with them. I run 40-45 miles per week, up from 30 a few months ago. I would like something more cushioned but I don't know what. I tried the pegasus and found them too heavy. I don't know much about different brands and what is out there. I live in the UK. I do mostly steady runs of 8 min/mile and a 5k every now and again (current pb of 19:12).
