FS: New Balance 800MF, Men's 8.5

I bought a pair of New Balance 800MF in Men's 8.5 size. They are recommended to promote a midfoot strike, as Chi Running emphasizes. I used them for a few runs and do not like the way they feel. I like to land slightly ahead of midfoot, toward the ball, and these shoes don't let me do that. They have 17.74 miles on them according to my equipment tracker!

They go for $109 brand new at zappos.com. I'd like $50 plus $5 shipping, paypal accepted.
