I've switched them out for performance purposes. The original laces were to "slippery" due to the kind of glossy material it was made out of, so
it kept becoming undone. I bought regular flat laces and laced them on with ease. The only obstacle is where the strap lies, but even that was easier than I
expected. The result? The best decision I made. It is SOOO much easier to tie and never comes undone. I highly recommend it if you want a better performance.
