The Romaleos are probably the most popular lifters on the market right now. They do sell out fast due to a combination of high demand for a shoe that is well built and also Nike being a bit slow on the restock so colorways sell out fast because Nike doesn't always announce when they will come back in stock. The colorway I bought I have not seen them in stock anywhere else since I bought them, so I think Nike is a little slow responding to the demand of this shoe, which of course is very frustrating for customers. FWIW, The Savaleos (I know they're not the same shoe) do tend to stay on the site longer as they are a little less popular.
