I have a pair of New Balance 1500v2's that I just started wearing this week and the insole in one of the shoes is slipping backwards sometimes while I am running, particularly when I run downhill. This is the 5th or so pair of 1500v2's that I've run in and I've never had this issue before.
I do prefer to keep the insoles in these shoes but the slipping is an issue. Is there some kind of adhesive or other strategy you have used to secure insoles? The insole is just settled loose in the shoe at the moment.
Thanks
