I hope this is a simple general question. I am looking at training in a new style, and I was told they do not wear shoes to train. This style is derived from an Okinawan style. I have trained previously in Chinese derived styles and always wore shoes. I'm just wondering if all Japanese/Okinawan styles are shoeless, or if this is just a randowm thing. I haven't been personally exposed to enough different styles to tell. Anyone have any info on this?
