the TX3 design is restricting the room/space to push the foot into the boots. I've own 3 pairs of lashed double boa and a couple of other branded boots. Lashed double doa has been the most comfortable, and easiest to put on and take off the boots. The new 2026 design feels stiffer and is very difficult to put on. Once managed to push the foot into the boot, The sizing feels pretty mush the same as the previous years boots I have. The new tongue cover design also make it a bit awkward to put on the boots, the Velcro on the tongue cover will stick to your snow socks and damage the sock fabric. If you have premium snow socks, you will have to be very careful when putting on and taking off the boots.... but I think ultimately you'd get your snow socks get damaged by the velcro on the tongue because the tongue cover is going to be in the way when putting and and taking off. Purchase a new liner is like $180 which is like half price of a brand new boots... if the liner is priced more affordable or with discount I would replace the liner for my newly purchased lashed double boa boots.
I typically buy a new pairs of 32 lashed boots each season because I do experience that the boa tends to get loose at end of the season (does not seem to be fully broken, it is just that I might find the boa popped to loose position easily itself, not sure what caused it. It is just that I need to retighten it when I find it gets loosened). I like I can wear the lashed double boa boots on the 2025 year model or before all day without any pain points, very easy to put on and take off. the 2026 model I'm not sure on the comfy side perspective. Maybe changing to another liner would make a difference?
