I noticed a problem when in-line skates first came out. People were hurting themselves while trying to stop on these skates. I realized a way to design a brake for the front of the skate that allowed a much quicker and safer learning curve when it came to stopping. It also became versatile with being able to stop going forward or backward.
Being a great demonstrational product allowed me to create commercials that received top advertising awards like the Cleo awards and several others. SEE THE AWARD WINNING SPOTS ON MY WEBSITE AND SEE IF YOU CAN FIGURE OUT WHO THE VOICE OVER IS ON THE COMMERCIALS. (Discovery Channel)
Skids is a bracket that mounts to the inside of the in-line skate blade The material is a glassed filled product called Zytel designed by Dupont inc. My design required that I put channels in the bracket to apply more strength and less material. The bumper is designed to allow you to drag your toe for stopping and is made out of urethane from the kryptonics corp. It’s the same material used for skate wheels. It has to have several durameters of hardness for indoor and outdoor use. We also had to take in the factor of rebound in the material so it wouldn’t bounce when trying to drag it on the ground.
