I have absolutely no feeling, as they should be the top search in google. I do not use the .com or the .net at the moment, like I pointed out. I was just asking if they are a business called SoleSearch, why settle for the domain sole-search.net? It's fairly easy to come into contact with the owner of domains if they are not available.
I'm sure all of their customers find it in the app store and that's why they've never worried about it. But take a successful app like angry birds for example. If I go to angrybirds.com, it takes you to their shop where they earn additional streams of revenue. If these guys want to create something special and "be bought out by yahoo for a billion", in my opinion they need to offer something more to a customer than just the name, address and phone number of a sneaker store. It's all stuff I can do myself by using a free app like google maps.
