So, I'm doing some XC this fall. I'm old, and haven't run in XC flats for a while. I have no problem with road flats, and I bought a pair of Nike Zoom Forever spikeless XC flats. The heel on those is a bit lower than I'm used to, and I'd like to buy some heel lifts for them.
Any brands or type people have had luck with? That don't move around, etc.
