Russ makes excellent points.
I also own both Camino GTXs and Tibets, neither leather lined. I have a set of Caminos I will sell, see below.
I archery hunt, CO in Sept. High elevation/very steep. I have many days in both boots with light to heavy packs. I TOTALLY second Russ RE boot weights, heed his words-- The Tibets are heavy and you will know it when you are wearing them. In fact, if you plan to use them, I highly recommend training with ankle weights in order to simulate boot weight when hiking in lighter footwear. The Caminos are notable lighter than Tibets, but sacrifice almost no support (in my estimation). I LOVE my Caminos, best boot by far for me. I have many hours with 35-60lb packs while wearing them. Caminos are amazing for side hilling, steep/rocky climbing and back to back days climbing. I find the Camino's sole to be incredible "accurate" (for lack of a better term) when climbing in rock. You feel like a mountain goat and simply know where your foot is at all times when you're on rock in the Caminos. I find the Tibets to provide great support and better for extreme loads (i.e. over 75 lbs for me) , but they are so big, they feel downright clunky sometimes. Solid, but clunky. They also take longer to break in... as in, do NOT take them hunting right out of the box. Tibets for me took about 4 days of real hiking to break in, and be sure to get them wet once while hiking to help the process.
Notably, the Tibet's have fewer lacing holes in the lower foot. This means that the don't extend to the toe box area, so the toe box is huge and has no way to adjust. The plus is that the toe box on the Tibets is cavernous and your toes have space. The downside is that you can't snug it down. I HAD to install aftermarket insoles so my foot would lock in better. Once installed, the boots are bomber. The Tibets have a phenomenal lacing system, best I've owned... one step better then the great system that the Caminos have (except for Tibets not having enough lacing points below the ankle). The Tibet lacing systems is *great* because the heel lock eyelet has a cam lock built it. Once you tension the lower laces, you close the heel lock eyelet cam and "voila" the lower boot tension is then completely isolated from your chosen upper boot tension.
Unlike Russ, I would not own leather lined boots. They take too long to dry and grab my socks when damp. My feet sweat when it's hot and September can be 80 degrees or as cold as 15. I don't want a damp liner, damp liner = sock friction = blisters in my world. Nor can I take a chance on soaking an all leather boot and having no way to dry it.
In summary-- You can't pick a loser with either boot. I like Camino because it's lighter, still offers tons of support and has an accurate sole.
**FYI- I have a set of 11 1/2 almost new Camino GTXs (Goretex) that I will sell. I have the original box and these boots also already have a set of $40+ thermo forming insoles in them, which still can be re-formed 3 more times (put in oven on low, follow directions). I also have the original insoles.
Used them four days, so they are broken in but just about new. They were a fraction too small when my feet swelled a bit and my big toe would just kiss the front of boot on steep descents, so I moved up to 12s. I will let them go for $135 plus actual shipping if you or anyone else is interested. If interested, PM me. Original poster has first option on the boots.
Hope this helps!
