as said before - 6 marathons in Boost - is that enough?
My current pair (about to be retired before Frankfurt this weekend) have done London 2014, Boston 2014 the week after and then Liverpool a few weeks after that - plus all the training for Frankfurt on Sunday - a few half marathons in between for fun! Still as soft as day one - a little pf the spring is gone but only a fraction. The durability is fantastic. my only wish is that they would put the continental rubber sole on all models for grip but aside from that there is no wear on the sole at all (i do mid foot neutral strike though). I use the energy boost though not the Boston boost.
i'm in a pickle too - went for an easy 15 on Saturday and about mile 10 i was running down a pavement with railings on the roadside - got about 1/4 mile down and some workmen had blocked the pavement so it was either go back or jump the railings (about 4ft) - guess what i did - i got on the top then lost my footing, went airborne and landed on my thigh on the top of the rail then down onto the road - probably looked rally funny and i can see the funny side except for the monumental bruise and dead leg i know have. Tried a gentle 4-5 last night and it still hurts but i can move it - i think its going to be one of those where i am running in pain but i can block it out and maintain pace. Ice and compression between now and Sunday. Is a dead leg that bad an injury to run on? Could i cause any other damage say 20 miles in?
