Toe Spring
The Toe Spring of a last, shoe, or pattern is simply how much the front tip lifts off the ground. A stiff hiking boot may have a 15mm toe spring, while a slip-on casual shoe may have a 5mm toe spring. As a general rule, the stiffer the shoe sole, the more toe spring you need for a normal rolling stride. You will see that a women’s high heel shoe has no toe spring.
