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.
was looking at doing this before signing up for Frankfurt but struggled with the flights - what flights have people managed to get to Valencia - i could not find anything going direct? Maybe i was just looking wrong
got the first 20+ miler in the bag this weekend - 23.4 miles on saturday (3h 10mins). Its always a big psychological barrier that first 20+ mile run in training - hoping to get another 3 or 4 in before the taper starts.
on the subject of hotels etc in case anyone is on the same : flying from Manchester on Lufthansa Friday lunchtime - staying at Holiday Inn Express.
