Years ago, I started with Rotcho jungle boots. I wore those things into a mess of cracked, "leather," (polyurethane) & frayed, "canvas," (polyester). Then, I snatched up a pair of no-names from a Goodwill. Mediocre quality control & a design built to chaff kept those things off my feet for anything but the lightest of use -- much better accommodated by even the simple Croc. Next, I tried 5.11's own spin on the same concept: the Speed 3.0s. They still wear well, even now, once I wore down those side vents; frayed nylon at the ankle & all.
But these? After some Castile soap, neatsfoot polish, new insoles, trimming of some loose hems, & a little reshaping of the vamp to fit me just right, these are the finest I've worn thus far. I think they'll perhaps outlive me, given half the chance. And, no less, at an unbeatable price.
