I've got a pair of 5.11 Tactical Boots, that are the most comfortable boots I've ever owned.
After 3yrs, the zip on the side went, so I superglued it shut and have worn them for another 3yrs.
Keep them clean and (slightly) polished to keep the leather in tact; they'll last forever.
Seen me through all weather (sun, rain and snow) in CQB and woodland.
I'd never play in anything other than a decent set of boots, looking after your feet is just as important as your eyes.
After a stunning "John MacLaine" moment of sliding down a bank and over a sticky-outy-rock, followed by a trip to A&E with a VERY swollen and painful ankle - the Doctors assured me that, for the most part, the only reason I wasn't on crutches is because my boots took the brunt of the hit.
