From "Notes On Long Distance Footwear (2023 Update)"
Section: 3-Season (Mixed Terrain)
In an earlier incarnation of this post, we wrote: "Scramble's ideal [3 season] boot is yet to be invented, but it would likely be a cross between the Spursinn Approach Shoe (~80%, see below) and [... the] Meindl Desert Fox (~20%). Taking the Meindl's drainage ability, a little of its ankle support and some of its outright toughness and keeping the fundaments of the Spursinn, you'd have a great lightweight scrambling boot for all but the non-winter months". Almost immediately after posting that, we stumbled upon the Super Ferrata MC LTH boots ("SF" from hereon) and a couple of us have been using the SF for most of our non-winter treks for the last three years.
What's quoted above is a pretty good summary of the SF approach / speed hiking boot. It's extremely tough, it drains and vents really well (via its side panels), and as you'd expect from an "approach" based boot, it's outstanding on rocky terrain. It provides a little more cushioning and support than the Spursinn and the Perwanger leather upper is extremely durable and has natural water resistance (without the need for any further proofing).
