Garmont T8 NFS vs. Belleville One Xero vs. other modern combat boots. Best boots for performance, support for heavy rucks, and durability?

I personally use Belleville Mini-Mils for everything except cold weather operations. The best boot is highly subjective. Both of the boots you mentioned are excellent, I would probably go with the One Xeros over the Garmonts.

I used T8NFS through bolc, ranger, ABN operations, and day-to-day wear. Love them, they come broken in pretty much out the box. Only downside is they take a good while to dry, and the laces that come with them get caught on everything in the wood line.

I love the Garmonts. I think I put over 1000 miles on my pair before the shoe laces snapped and I decided it was just time to replace them. I switched to Danners though, and Danners have been the most comfortable out of the box boot i've worn so far. I've had them for about a month now and they're still insanely comfortable and form fitting to my feet.

I've rucked about 400 miles now in mt Garmonts and they are great. Very light and pliable. It took me a little longer to break mine in since I have orthotic inserts I use for my feet. After that period I no longer get blisters. They are great for everyday/work use as well.

What boot would you recommend for IBOLC?
