I thought I'd say a bit more about my experiences so far practicing Parkour with my KSOs.
It makes me think back to when I was learning to leap over a wall using my hands
(kong/catpass), I always scraped my skin off the end of my pinkie. I thought I'd try wearing
gloves to stop that, but I ended up with a hole in my gloves! But as I became more
practiced, I stopped scraping my little finger off. An improved technique was the answer.
So when started using KSOs, I could really feel how my feet slid against the walls. My
previous Parkour shoes were really old and I managed to scrape all the sole off till there was
literally nothing left! Is it really a good thing to allow your feet to slide? Perhaps it is better to
stop your feet scraping across surfaces and use better technique to contact on to
just like I used my hands to get over a wall. I now am much more delicate with my feet and
always think after a sloppy landing "ah, that could have been done much better" where I
wouldn't have before. It is expensive rubber to burn!
My balance is much easier now, the KSOs allow my feet to conform to walls and rails as I
walk on top of them. And they're so silent which is a good indication of efficiency.
