New Shoes Too Big
If you have bought a pair of new shoes that are slightly too big there are many products on the market to fill up your shoe to make it fit. The first thing to try is an insole which in either a rubber or leather fabric to fill up your shoe all over. If the problem area is the heel and you find that your shoe flips up and down as you walk, try attaching a stick on heel grip preferably in a leather fabric. This will fill out your shoe in the heel area and hopefully keep your shoes on. If you find that that the balls of your feet are rubbing, it may be because the shoe is too loose allowing it to move around.
There are lots of great foot petals on the market which can be bought from either a pharmacy or supermarket and in most shoe stores. This little rubber pad will stick to your shoe without any adhesive and stop the ball of your foot from moving around.
New Shoes Too Small
If you couldn't resist a pair of shoes that happened to be slightly too small then don't worry, a cobbler can help. The problem is that when it comes to stretching, shoes can generally only be made wider - for obvious reasons they can't be magically make longer! If you have a pair of sandals or shoes with a buckle strap, extra holes can be punched it to loosen the fit. If you do happen to buy shoes that are too small, try to stick to only purchased open-toe styles. This way your toes can just poke out a little more than they should.
Slippery Soles
If you find that your shoes are slippery, simply get a piece of sandpaper and lightly sand over the sole of the shoe. This will lightly scratch the surface of the shoe sole and give you the grip you need. Alternatively, take your new shoes to a boot maker and have them attach rubber soles to the bottom of your shoes. This will not only protect your shoes (you can replace them when they're worn) but also add grip.

New shoes on budget day is an unusual tradition among Canadian Ministers of Finance. The tradition holds that the Minister of Finance should purchase or wear new shoes when the budget is delivered.
The exact origins of this tradition are not known. The observance of this tradition has been inconsistent among federal ministers; indeed, for two or three finance ministers, this tradition only holds if "new shoes" is interpreted to mean "new footwear". It also makes appearances among provincial finance ministers.

Her mother, admiring the new shoes "the color of a rose," explains that they must be put away until Silvia grows into them. Silvia sleeps with her new shoes, makes doll beds out of them, and uses them as a train while she waits for many months until they fit her. Finally the shoes fit, and she wears them to town to mail a letter to her aunt.aunt.
