Pros: Outstanding adjustable last width, buckle extender
Cons: Power Strap length, Calf Spoiler Removal
If you have wide feet, this should certainly be on your list to try. At 10.5 shoe size, EEEE width, this boot in 27.5 was PERFECT for me. Moving from a Rossignol Sensor 70, I compared these Head boots with Tecnica Phoenix 14 HVL 2012s. Hands down a better fit with a much nicer buckle system.
With the original liner it's quite tight in the calf area (for a 17" calf) and the power strap is of optimal length if my calf and leg were the size of my forearm. You won't need to crank these things down all the way. You can pretty much stop blood flow by the third notch. The thread pitch on the micro adjusts could be a bit finer as one revolution is not quite providing the granularity of range I'd like.
The adjustable spoiler on the back of the calf is not removable without modification (i.e. drilling out the bolt) as they used a captured end on it. Looks like it will be easy to drill though. This would remove almost an eighth of an inch thickness and about a quarter inch of rise above the top of the cuff.
The liner is a bit on the thick side in the calf and cuff area while the toes taper on both sides with a different, narrower profile than the boot's foot shape. The sides around the ankle pads are not durable as removing them only a couple times has started to tear up the foam (not covered in plastic or mesh). Looks like an aftermarket liner (e.g. Intuition Universal) would benefit here for large calf.
Happy with the control, it has been a wonderful improvement. Foot last is still good for a EEEE width.
