Step 1: Learn from the homeless
Step 2: Tear a strip of paper
Step 4: Fit around the end of the toes
Step 5: Prepare to push the paper into the shoe
Step 6: Drag the paper into the shoe with your foot
Step 7: How it will look
One set of newsprint strips will last for a couple of weeks, maybe longer before it needs replacement. Leave the newsprint inside your shoes when you remove the shoes at the end of your ride.
Step 8: A warm winter glove with mitten cover
I wear cotton jersey gloves below about 45 degrees F. When the temperature drops below 40 degrees F. I wear these glove/mitts, but I am apt to pull the mitt cover away from the fingers until the temperature drops below about 35 degrees F. When the temperature drops below about 25 degrees F. it is time to add something extra. My extra is strips of newsprint, just as with my shoes.
