It's been awhile and I have a question. I am trying more and more to do the slide technique but it is very difficult. I have watched countless videos and I have a confident understanding of how it works. But here is the question, what is a good pair of shoes to wear when practicing/attempting this? Right now I have a pair of new balance 409. Plenty of flex in the foot but no slide ability to speak of. Any suggestions? And yes, I have removed some of the rubber pads in the footboard as well as switching the plate around. Thank you for any sound advice.
