I have used the lifting of my right foot to reverse on both my B21 and now my B26 for some time now. In fact whenever I purchase a new set of workboots I immediately take them to the shoe repair guy and have him add an additional strip of rubber behind the toe protector on the right boot. I have found that over time lifting the pedal with the same right boot caused the leather on the top to wear prematurely just where the steel toe ends. Adding the piece of rubber ensure the right boot lasts longer......
You might save yourself some money by putting some rubber on the bottom of the pedal instead of on ur boots. Just sayin'
