I really like my adiStar's. First pair of lifting shoes for me so I cannot compare to others. (birthday gift...and I hope they last for years!) They are extremely comfortable and best purchase I have ever made since lifting. I read the stuff about being narrow and was hesitant. I thought my foot was wide (shoe guy gave me wide running shoes) but they fit perfect. Ordered a size 11 which is the size of my leather dress shoes. I heard over and over that was a good fit comparison. adiStars: 11 Leather dress shoes: 11 Nike golf shoes: 11 1/2 Chuck Taylor: 10.5
Big fan, but I bet I would have been a big fan of any shoe I got because finally I wasn't squatting all wobbly like with my chucks. They feel really well constructed, but again I have nothing to compare to wl shoe wise. I also deadlift in them. At first I deadlifted in my Chucks. Since I have short arms it is tough for me to get in a good position. Deadlifting in these shoes helped me get into a much better position. That is more info than you were asking but just giving my experience. My wife hated lifting in her Ironwork III's and went back to flat bottom shoes.
I did research for several weeks, so best bet is what they suggested. Google the heck out your questions.
For what it is worth, here is where I purchased from:

Very quick and good service.
Oh, and mine is an inch heel according to the tape measure from the back.
