Wondering what kind of shoes (footwear) do you wear when you shoot pistol and why?  I know it’s really individual but I would like to get some ideas. 
I am a newbie to the bullseye pistol shooting that started this summer.  I tried a few different shoes, hiking shoes, military boots, etc.  So far none of them are perfect fit for me.  Funny but my most favorite shooting footwear so far is a pair of flat-sole sandals.  Not 100% sure if they are NRA and CMP legal though.
