Sorry! I missed your post...
I have crashed in SMX, I ran to the car in 100kmh or so and the left feet went under the car, in the front of this boots there are some protectors, but during the crash, these have ripped off and cut my leg. I think, another, more protective boots, could save me two scarfs on feet, after all, none of boots could save me from broking the ankle
add Alpin super techs, yes, they are with separate inner boot, are very comfortable and durable.
and another bonus? They look very "racing". With these boots I have 2sec better times in circuit
