Buying Parkour shoes?

So this is probably a daily question on here but I couldn't find the answer so here it goes. I have been doing research for buying a Parkour shoe for beginners and I have found that cheep seems to be the best bet. I am nervous however to get a cheep pair of shoes because I don't want to damage my feet from improper arch support or any other poor design aspects (I have high arches). What would you suggest to get around this problem?
