Today is the third day of our marathon and the theme of the day is : How to convert sandal last into a platform last.
The sole surface of the platform last is always must be flat, it doesn't have curves which are true, as our foot has them and so as most of lasts. Therefore, to work with platform you must have a special last with flat bottom. In today's tutorial I will show you how any shoe (I show an example of sandal last) can be transformed into a last for platform shoes.
1. Note the curve, which is on the last, which I mentioned before.
2. Now this curve should be removed, that is to make a flat surface of the sole. For this, I must grind the bottom of the last with a file, holding the hand 90 degrees straight so the grinding will be even through the all surface, so you wouldn't get one edge of the last lower than the other. So grind slowly and constantly check if it's even by applying the ruler to the last as shown in the picture below.
