the boots are midflexing but a bit more stiff than anything else, i have around 40 or so days on them and they are still as stiff as i bought them, the liner is ok not too hot or cold but the jbars i cant seem to adjust. my right foot is a bit smaller so my heel comes out a bit and if i tighten them up too much i lose all feeling in the foot. laces are bomb proof still original. boot is a bit wide but still fits in all my l/xl unions, boot size 11. if they had a softer liner like the nike zf1's or any salomon or ride it would be a lot better. i went from the zf1's back to dcs for the outerliner. the zf1s got too soft too quick, but if you are into that then go for it.
