Toughening up the feet

[wanabe1026]

I was told that it is a good idea to start toughening up my feet so I don't get a lot of blisters and foot problems on long rucks and stuff. I backpack a lot and I very rarely get blisters but then again I've always had great boots, always broke them in before doing anything strenuous in them and I'm always on trails. One trick I heard from someone was to soak my feet in epson salt. I was wondering if you guys had any tricks up your sleeves.

I did a search on this subject and didn't really see anything. If I need to look harder just tell me.

Thank you
