Last September I asked about custom-made mountain boots. GregorC recommended Proalp.
Let me say I can't wear their boot, even though they made it 2x, measured foot several times, I warned them about foot peculiarities, I was at least 6x in their shop, 2x sent boots by post...
Anyway I have a nice memory worth 180 euros, but how I'll hike with kids in mountains I don't know.
Conditionally I could put them on if no laces in first two holes, but can't wear them because they simply made them too low in front and without "indent" under big immobile toe. I did that myself now for a fix, but still find the boot too narrow and low in front.
