Pro Designed has been in the hand manufacturing safety gear for the skateboarding community for decades. These are premium Safety Gear products hand sewn in Texas by Wild Bill and his team for skateboards looking for the best protection they can get.
The Super Single Knee Pads are like pillows for your knees. They may be bulkier than other brands but skateboarders like Steve Alba and many other skateboards skating well into their 50s have been using them for years so obviously they provide the protection you need to keep going. Of course anything can happen but it is always a good idea to do what you can to keep skating as long as you can.
