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?
used to run in the Adidas Glides and hovered around the 3.30 mark for the marathon - consistently had niggles around the calves - moved to the original Energy Boost when they came out and initially had trouble with the snug fit aounnd the top of the shoe - i remember them rubbing a fair bit but after about 10 runs they began to fit a lot better. Performance wise all i can say is that 'it does exactly what it says on the tin'. I have never felt so much 'rebound' of a pair of shoes and for a shoe that was so light when normally at that weight you are talking about low cushioning shoes. The cushioning was unbelievable yet you felt like you where being propelled forward with every stride. I am not an Adidas Sales Rep by the way
Anyway - i have now done 6 marathons in them, had at least three pairs now and my new record is 2:57:27!! I am not saying they will make you run faster - although they may help - but i think what they offer is the 'feeling' of running faster which in turn gives you the confidence to actually run faster. I know in training because i feel so comfortable and almost 'bullet proof' as since changing my injuries have reduced dramatically, i feel like i can push it all the time which has resulted in the dramatic PB change.
My advice - you have to at least try them, they are different and to me a fantastic 'invention' that has revolutionized my running but probably more in a mental than physical way - will it help you? That is something that i cannot say but i know they are the reason i am now sub 3hrs.
