These shoes won't be broken!
So I bought a great pair of Merrell hiking shoes back in February and have been wearing them regularly since I got them. They're certainly well "broken-in" already; I've probably walked about 75-100km in them, and yet I still get blisters! It's always in the same spot- the inside of the arch of my foot, on both feet. Bandaids or moleskin help a bit, but only temporarily.
Does anyone know of a way to fix this? The shoes are wonderfully comfortable otherwise, and great quality, and I'd rather not have to get new ones if I can avoid it, but I have a 40km trip coming up soon and don't know how I'll manage with the shoes as-is.
