New for 2025, Spine designed this boot with carbon fiber plate in the outsole for more torsional stiffness. Compatible with NNN, Prolink, and Turnamic skate bindings. Length runs true, and width on the wider side. We recommend lacing through top eyelets to secure ankle more snug. 

We measured the inside lengths (stuck tape measure inside boot with insole in) and got the following lengths:

40 Euro: 10 1/8"

41 Euro: 10 3/8"

42 Euro: 10 1/2"

43 Euro: 10 5/8"

44 Euro: 11"

45 Euro: 11 3/8"

46 Euro: 11 5/8"

Generally for summer sock thickness and to ensure toes aren't rubbing in front, you want a boot that is your foot length plus ~1/2-5/8". You can measure your foot by backing it up against a wall barefoot and measure out.
