Fuses for skates

I cringe every time I see the horses in horror films. You know, the same thing happens to everyone! We all know that we must be careful, but no one is safe from harm, the more-with such terrible things, like the blades of skates.
Kootsu defense mechanism protects the blade skates, and a person from this blade. Special technology will help to establish a defense mechanism, without any effort and risk, and the rubber sole of this device will allow you to walk on skates as in ordinary shoes.
