Over several Caminos we have been 3 sock-layers pilgrims.
Inner 'coolmax' wicking, mid light mohair, outer cushion sole mohair (Sportsman and Companion -short). No blisters and any sweat absorbed. Corrymoor's mohair does not smell and does not need washing, just needs to air-off overnight. 2 sets mohairs and 3 r 4 pairs inner lightweight wicking socks were sufficient.
The only problem is that you do need to buy shoes/boots when wearing them so not a solution if you already have those.
Corrymoor (UK) ship their mohair socks to other countries and I see the OP
@Michaelg1962 is in Australia but this might give some ideas....
Buen Camino
