I have been rollerblading for a couple of seasons and have tried a variety of blades during that time. If you are looking for a new pair of boots, I highly recommend the K2 Moto Mens inline skates. I have been out on my new pair about 15 times this season so far and they are excellent.
I personally skate on the 84/80mm wheels, but they also come in a 90mm version. The most important attribute for me is their speed. The skating is more effortless with less friction than other blades I have tried.
The boot has the legendary K2 comfort and provides good ankle support. They are also very quick to lace with a quick lace system, which is a nice addition. When you buy, try to size a snug fit because they will expand a bit overtime as you skate.
For Women, K2's comparable boot is the K2 Celena 08. Obviously, I have not tried those but given the success of the Moto for Men, I would expect these to be excellent also.
