Don't chunky shoes create a 'cattle grid' effect with the roller Paul??
Not that I've noticed - but tread is now well below 3mm.
I usually wear a pair of ScrewFix safety boots (look a little like hiking boots - these are similar:

Use the boots for work, but as ankle support is important, I tend to use them for general wear. Size 10 are small enough in RTA. When marshaling I have a pair of Doc Martins, in a 10, have to take a little care driving up Prescott with those on
Cheers,
