Kate, this is mad, its like you are me or something!
I have a husband who is exactly the same as yours, I have to sneak around buying stuff, as he thinks its ridiculous, and I should be able to run in any old crap! He gets annoyed at the amount of shoes in general that I own, and always moans when I buy running shoes (with MY money, I might add
!).
Like you, I also slightly over pronate, and like you I was recently recommended the Brooks Adrenaline GTS8, and like them!! Bizzarre eh?? I was wondering the same thing as you as well! Did you also get a half size bigger? That's what they told me to do.
I felt a right pratt in the shop as he was shocked that I had never been on a treadmill, and when I started walking I was very unsteady and kept nearly falling off!!
I am trying to get a lot of miles in at the minute so recently purchased a pair of Asics 1130's as well, which are as light as a feather, and am so far pleased with. I don't know whether to stick to the Brooks for longer runs and the others for shorter runs? Either way my next pair I would buy online and wait until next seasons colour comes out so they are cheaper.
