I'm the inventor of the Shintronic. We made some changes by leaving the outer padding away this season (better fit, less volume, less pressure) and we provide an optional elastric strap preventing sliding up. If you have any specific questions, do not hesistate to ask via email@example.com
. We receive very positive reactions from teh Park etc. It is not only about preventing 'shin bang', but you will enjoy the power. grip and control effects. Not happy, just reply.
