Hi, There is a new version of the Forma Terra out called the Terra EVO. It now includes a hinged feature called FCS (Flex Control System) which strengthens the ankle area to prevent side to side flex and give much better ankle support. They also beefed up the ankle cup and plastics reinforcement. It is waterproof as before. There is also the Predator 2.0 boot out now by Forma which is their premium MX boot. It is available in MX and a black Enduro version with tread sole. In regards to the Forma Terrain TX and Terrain TX Enduro models, I have it here and also a pair of Sidi Crossfire 2 TAs. They are both in size 46 Euro. I weighed them on my postal scale and they are: Forma Terrain 4 lbs, 5 oz. SIDI 4 lbs 7 oz. I also weighed my Toucans and in size 44 they are 3 lbs 5 oz. I expect most MX and adventure boots to be about in the same ballpark as these. The SIDI boots have more deluxe memory foam inside so from a creature comforts standpoint they are more plush, but in terms of protection I don't see much of any difference in the protective elements between them and I think the Forma Terrain TX boots are the best value full protection MX boot. They are not waterproof at all, but will be fine in puddle splash or a little rain. If you put your foot down into a puddle or stream, the MX boots are going to get wet inside. In terms of walking around, MX boots are not very good for it, which is preferable to me as I want a really stiff boot with a stiff sole for on bike protection. I am mostly 90% dirt / trail riding these days so it's the best boot for me. I am so used to MX boots now that I just wear them all the time no matter what I am riding, and they have the best protection. There's no free lunch, so a lighter boot that is easier to walk in will not be as protective as an MX boot, and an MX boot will not be the greatest to walk around in. I would suggest one possible compromise solution for an ADV rider would be an ADV boot like the Alpinestars Toucan, Corozal or the Form Terra boots. All of which are waterproof and OK to walk around in. It's basically like wearing an army boot in terms of feel. Or, you could wear MX boots and carry a pair of sport sandals or tennis shoes in a bag on your bike if you will be off the bike and walking quite a bit. I guess it depends on how much walking you will be doing. Guys I ride with do use ADV boots on the trails we go on and they work fine for them. I have some existing ankle injuries and I also wear knee braces so it's MX/Enduro boots for me. I was not unhappy with my Toucans but I know that I'm a crasher and in my crashes where I was wearing them, I would have been better off with MX boots in terms of injury protection. Now these were real crashes, not just dropping the bike on the trail or tipping over. For that kind of stuff I think an MX or ADV boot is going to be fine as long as the ankle flex area is really supported so you don't twist an ankle or hyperextend something if your bike lands on the ankle. But for a big crash I want my MX boots. I hope this was helpful. Here I have a video and about 1/3 of the way in I go over some of the new released Forma boot models for 2018. I am not a professional narrator but I eventually cover everything.
