So I'm 2 weeks out from a marathon, and took today's long run as the chance to break in a pair of Lunaracers I'd been saving for the occasion, based on lots of very good online reviews. I'm not 100% sold, though.
While I like the lightweight feel and the cushion/drop feel good for me, I was a bit concerned by the relative lack of forefoot/midfoot cushioning compared to the heel - any better suggestions for a midfoot-striking neutral shoe wearer running around 3 hours for the marathon?
