Roger,
“What is the weight limit for discussion of trail footwear on BPL?
Anything above 100 g is obviously far too heavy …”
OK, that is around 3.5 oz. Per pair or per shoe, that is way lighter than anything that would be durable and strong enough for hiking on the extremely rocky and uneven ground here, not to mention the mountain bushwhacking that I love. During much of the hiking, the shoes are at sharp angles to horizontal, both sideways as well as forward. In other words, one often does not get to put the foot flat on the ground; but rather, the shoes are forced to fall at a sharp angle sideways away from the horizontal. This puts a lot of rotational force on the shoes and soles to twist on the foot. Of course, much goes into learning how to step to avoid these forces as much as possible. And shoes or boots designed to help with that are key. That is where the custom Limmers shine, but from what you say, they are not germane here.
I’ve also found, that no matter how good the WPB is, in the long and powerful downpours we get here, cloth or mesh outers will soon fail and the inside will soak. Since I find SOME mostly leather boots with WPB will allow me to hike with dry feet all day in the foulest weather, that is another reason for heavier boots. I don’t find they tire me especially at all. The older boots, which ran over 4 lbs (~ 1.8 kilos), would tire me now. I keep a pair of custom boots from John Calden of Estes Park CO around as mementos, but the extra weight would be way too much at my age.
I’ve been talking with Peter Limmer here for several years about lowering the weight of custom boots; but from what you state, don’t think we are anywhere close to the weight range you have in mind.
Agree that the superstructure of UL shoes will probably wear out before soles, so the resoling issue on UL shoes is academic. It’s also helpful to buy from large outfitters with a wide selection to try on. That way, I can find a best fit in an hour or two, when orders and returns would take months. I’m dry, comfy and without strain, and that is AOK for me. Imagine you are also OK with those UL shoes (recall a photo you posted once). Will leave it at that for now.
