Most every brand (only exceptions that come to mind are K2 and Full Tilt) will offer a range of boots in both 95 and 98mm lasts. Occasionally you will come across <95mm boots but they tend be rather specific and purely geared for WC race. But if you are looking at only 98mm boots then every boot brand makes them.
All of these boots will offer different last shapes compared to one another, along with different geometries and flexes. So, as mentioned earlier, definitely stop in to your local shop and find out which options will work best for you.
