The majority of pinholephotographic shoes are leather and will stretch and break in to the shape of your foot. Below are some tips to help with this process.
- Put on your shoes to walk around the house for short periods.
- Wear them with socks during the break-in period to protect your feet and stretch the shoes more quickly.
- Paper surgical tape or band-aids on hot spots can also help prevent blister during the break-in process.
Moisture and heat are the two things that make leather stretch.
Moisture: Lightly swab the inside of your shoes with rubbing alcohol or a damp cloth. Do not get the shoes soaking wet - just add a bit of moisture to the inside of the areas you want to stretch, just before you wear them around the house.
Heat: Blow dry over the tight spot for about 20 to 30 seconds, far enough away that you don't burn your feet. Then, take a quick walk around the room to loosen the shoe material while it's still hot and flexible.
