Regarding the lifts guys, you can get a lot of cheap ones, but you get what you pay for. You'll have to get a shoe size up as well to put them in and they work best in boots or high rising shoes. Don't expect to be able to walk too long in them either, you'll kill your feet. Prolong use will also tear up the inside of your shoes.
The best thing to do is to get elevator shoes. Some styles accentuate the fact that their lifts, so beware of sites that only show angled photos of the shoes. Also, they tend to exaggerate and say "you can gain 4 inches with this shoe" when in reality, you'll be lucky to gain 3 once you put them on. The best elevator shoes to get are obviously more expensive and from Don's. These shoes won't fall apart, but they're made from leather so you have to be looking for a specific style.
cheers guys.
