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.
Thanks!

Nothing will help if shoe doesn't fit properly. Last week I had 40km day with Keens I've been wearing 2yrs now, super comfy never any issue, but 40km is 40km and if even small extra pocket starts rubbing it gets bigger and bigger .. at the end I don't think I've ever seen such a big blister, had to lance it yesterday, half a liter came out, should have taken a pic



If you go with these on 40km trip you will pay dearly.

Duct tape the inside of your shoe where there's friction. It works!!!

Get a different shoe lol

I had my longest hikes wearing "crocs". I throw them in the oven at low temp, take them out, put an extra layer of socks and walk around while they were toasty and they would form around my foot with slight extra space from the extra layer of socks.


Not conventional and fugly but very comfy and breathable worn with a socks. Only shoes that don't eventually bother my feet after long hikes.


I used to start many hikes with hiking boots or shoes and end up ditching them for the crocs (obviously not in technical terrain).
