Bike shoes work well, but still needs tie down straps to prevent sway and rear wheel movement.
I like the Risk Racing MX Lock n Load better than the Bolt On System.
My current system for dirt bikes is 5 straps per bike without any type of wheel chocks. 4 straps on handlebars. One short strap on rear tire. I have e-track along both sidewalls and removable single ring Ancra points in the middle of floor parallel with the e-track. Bikes are side to side and alternating front/back. They are inches apart and don't rub each other. Even after many miles is Idaho washboard dirt.
