Another topic while I digest your post from yesterday on gels.
I have probably put in close to 400 miles in my current pair of trainers and so probably need to change them over the next few weeks.
I have a pair of Adidas Supernova trainers as I overpronate slightly.
I am going to get the current model of that same running shoe so as not to have any complications.
How best to introduce the new set of trainers - I am guessing during slow easy runs and over what period ?
Last time I changed trainers during marathon training I ended up with blisters.
