We angled the heels inward toward the center of the motorcycle at 100 and built in an adjustment screw so you can set them to be angled up where they hinge to your liking. They have a tall heel rest to prevent your foot from sliding down, can be folded up when not in use and stay in place with spring-loaded detents. They come with 3/8" mounting bolts and will work with all RIVCO (and most other brands) mounts. Polished to a flawless finish, triple chrome-plated, & inlaid with soft anti-vibration neoprene rubber. 8” x 5”
