Those look awesome. Do you know if they tend to run small, large, or true to size? I usually wear a 44.5.
They are sized in Mondopoint which is truer to size than any other measuring system.
Mondopoint 285 is a large 44 and 290 is a regular 45.
285 mondopoint means 285mm insole. so take a tape and measure your foot.
I wear 10.5-11 in Chucks and 44 in MMM GATs if that helps.
