I couldn't refuse the close-out price on these boots. Received them yesterday, then read all the operating instructions before putting them on. Size is 45 Euro. Unfortunately for me, Sidi's 45 is smaller than my Alpinestars SMX-6s, making my feet very uncomfortable. They'll get sent back as soon as I get a return Fedex label from STG; then I'll get a refund and purchase another set of SMX-6 (V2).
