Replying to Uncomfortable Feet

OK, so I've been having this problem with my boots where the outside edge of my foot (mainly from the 6th toe forward) goes completely numb after about 15 minutes in the boot, it gets so bad to the point my feet cramp up really bad and are completely uncomfortable. Will punching out the side of the boot some help? Anyone have any opinions on the matter? I dont have a wide foot so I dont know if switching to a wider boot will help. The boots fit perfect otherwise, toes are on the front of the boot until flexed etc... Any help would be appreciated, can't afford another pair of boots.
