SIDI Vortice motorcycle boots, size 45 Euro, 11 US.
These are the ultimate for street and track, with replaceable parts.

New $495. Worn for two rides for fit, approx 20-25 miles total, but still a size too big for me. I can wear thicker socks and with an arch support insert, but would feel better ordering in proper size.
Too late to exchange, so like new.
$420 shipped to 48 in US, FedEx.
