Even sith lords need decent footwear, and a few options are available to us.
Vader's boots are leather and military in style, with a round W-toe. The shafts are high, covering almost the entire lower leg. The detail on the shaft isn't so important due to the shin guards due to cover them. Still, you should go for as featureless a pair as possible.
It goes without saying - they need to be black. Comments from other Vader costumers suggest you must get a pair that your feet fit into easily. Even if you have no need to raise your height, cushion them with insoles. Remember you'll be wearing these for several hours and, once you're suited and booted, they're not easy to slip off for a quick break. If you're on a budget, you could get away with rubber or PVC boots, but they won't feel so good, look so good, last so long nor smell as good as a decent leather pair.
Who sells such things? Riding boots do the role justice. The price range is very wide, from amazingly cheap to spectacularly expensive. You can get them from equestrian supply stores. If you're shopping around for riding boots, familiarise yourself with terms associated with riding boots and what they mean. Some tall riding boots are as follows:
This is by no means an exhaustive list. You could try army surplus shops, or costume stores, but where you go really depends on your budget. Just don't expect to have an outstanding looking suit if you don't splash out for it!
I wasn't going to settle for anything less than leather - and struck gold with a pair of semi-dressage riding boots, after a fair bit of hunting. Hunting for boots, that is!
