I've got about 25 days on my Northwave Decades, I figure it's a good time to write a new review.
After about 5 days, I found that the footbed was really not helpful (surprise surprise) and so it was replaced with these:
Much improved arch support...
On to the boots themselves.
Comfort: They remain very comfortable and I have had no problem with warmth. They have not developed any pressure points like me previous 32 and Salomon boots used to. Dock 2 points for having to replace the footbed.
Durability: The Decades have lost very little stiffness. In addition, they do not show much wear, and appear to be holding up very well. My 32 boots by this time had started to show a lot of wear and the sole had started to separate. They also do not pack out very much. The quality of these boots is very very good!
Warranty: One of the inner liner laces was starting to fray, Northwave sent me a new pair which are a different design, and I got them in about 5 days. No questions asked. Thumbs up for good service. Faster shipping would be good, but no complaints.
Lacing: I really like the lacing system, I can get in and out of the boots very quickly. In addition, the SL system is warrantied for 2 years. I would buy this lacing system again.
Performance: This is my only complaint with this boot. Over time, it appears to be developing more heel lift. I may have to visit a boot fitter at the end of the season to figure something out, it isn't a big problem, but this is something that needs to be fixed for my to consider these boots again. It could be my small heel that causes it, but I would like to see a better system to anchor the heel in place. regardless of this, I don't feel like I have lost a lot of control, but it is not as precise as I would like it to be.
