I have a pair of Alpinestars S-MX-5 boots, size 45, for sale. They were a year old when the sole started giving. I sent it back to A* and they completely resoled it with full warranty (they even sent me a loaner pair of Supertech R boots while the soles were being fixed). Meanwhile, I bought a different pair of boots. So, basically, the MX5 I have is like-new in pristine condition. MSRP is $219.95. Yours for $150 including shipping. Let me know.
