Hello, I'm running a marathon on Sunday and recently bought some Scholls archy type insoles for overpronation which seem to work nicely.
My runners are mizuno wave inspires - cushioning and support... If I continue running in these without their original insole and with the scholls insole will I lose some of that cushioning? Should I instead tape myself a false arch and use the original Mizuno insoles??
Any advice would be gratefully accepted!
