Kung fu shoes are great for wing chun and such. But if your style involves more pivoting and movement or acrobatic techniques, then these shoes will fly of your feet like a greased pig with wings. Feiyue shoes are the best overall shoes for indoor kung fu training: light, cheap, great traction, and stay on your feet. These are the choice brand for most martial arts schools in China. In fact they are the same brand that the Shaolin monks use. If however you are going to do any training outside on concrete and such, then I would recommend something more durable like Adidas Samba indoor soccer shoes. This are made of strong leather and the soles hold up longer on rough concrete.
just to shoes, kung fu trainer is not the least requirement .The honest truth is that there are no real requirements to work as a kung fu trainer. There is no real sanctioning board. Anyone with enough money can open a school. Thats why it is important for prospective students to take a really good look at the teacher’s credentials and lineage. I you mean working as a kung fu trainer and someone else’s school, there is pretty much close to 0% chance of that happening and most schools will look to inside help from their own student body first.
Patience, understanding, and the ability to sometimes be tough are all important traits of a teacher of anything, in my opinion.
As mentioned, you can really begin teaching whenever you feel you’re up to it. Also keep in mind though, that if you’re anything less than black belt, it will probably be hard to keep students. Who wants to learn from someone that might not fully know what they’re doing?
Lastly, it can be hard to find Kung Fu students, period. Most people who have an interest in martial arts or mixed martial arts are too interested in more ‘mainstream’ arts to go off the beaten path and learn Kung Fu.
