Proper leather shoes

This is so true. It is so difficult to find decent walking boots without Gore tex or some other membrane these days. Meindl Borneos are one that are actually lined with soft leather. Really lush!

I don't know a single decent walking boot that uses GoreTex. GoreTex seems to be the stuff used in low grade machine made synthetic footware but I don't think I've ever seen it being used in anything properly made.
Good walking boots should be made on lasts, Goodyear welted and double stitched. GoreTex is reserved for the lower priced "junk" to try to make something cheap and half-way useable. Hanwag and Meindl, for example, still made good shoes even if the mass of what they sell is "junk"--- Meindl's Super-Perfect and Hanwag's Bergell cost over 300 EURO so while not expensive, still way more than most of their customers tend to want to spend, . There are also a number of makers that just do good stuff..
