That's the thing, your feet don't know you're not a "pro".
This is the best advice here. You have to go with what fits YOU, not just what someone else recommends. After hearing how Lowa boots are the best thing ever I finally caved and bought a pair of Zephyr GTX boots. Everyone said they shouldn't need breaking in and that they were like slippers from the first day. After wearing them around the office for a day mine left me with numb toes. TRurns out that wide, supinated feet with a very high in step do NOT work well with Lowa Zephyr GTXs.
I have personally found Merrells to be very good (ie comfortable and acceptably waterproof). I've had Sawtooths (ally as fuck but quite heavy), two pairs of MOAB trainers for just walking about when it's a bit wet and currently have a pair of MOAB 2 Tactical Response GTX zip side boots for the BB warz. Conversely I know plenty of folks that won't touch Merrells and that they fall apart after a few uses.
The one caveat I'd add to @clumpyedge's suggestion is that there is really a minimum I'd expect to pay for a decent boot that will last for at least a year of semi regular use, cheap chinese stuff may well be made in the same factory as the better branded kit but I can guarantee it won't be subject to the same design constrictions or QA. If you want value, get to Go Outdoors and get their discount card (which is about a fiver a year if I recall) and spend the same budget getting better boots at a discount. Great boots won't make you a better airsofter, but bad boots can ruin your day!
