A polyurethane sole, like the semirigid type, is an important part of making shoes. It's designed to give a balance between being flexible and firm, so it can be used in many different kinds of shoes. These semirigid polyurethane soles are made to support your feet and keep them stable while still letting you move comfortably. You'll find them in sports shoes, everyday shoes, and even work boots.

They're made from polyurethane, which is a tough man-made material that doesn't wear out easily. These soles are not too stiff and not too soft; they're just right for all sorts of activities.

One of the good things about these polyurethane soles is that they can absorb shocks, which means they help your feet and joints when you walk or do physical activities. They also keep your feet comfortable in different temperatures and are resistant to water and chemicals, which makes the shoes last longer.

Polyurethane soles that are somewhat stiff are regulated by a standard called IS 13893:1994. The Bureau of Indian Standards (BIS) decided to follow this standard after the group responsible for footwear agreed on its content, and it was approved by the chemical division council. This standard lays out the rules for how these specific types of shoe soles made from polyurethane should be made, tested, and checked to ensure they meet certain quality standards.

REQUIREMENTS FOR IS 13893:1994

1. These soles must meet certain physical standards mentioned in the rules.

2. The sole should be not slippery, or it can have a different design as long as the buyer and seller agree.

3. The thickness of the sole must be at least 10 millimeters everywhere when you measure it using a specific method called IS 12240(PART 1):1988.

4. To make sure the shoes meet the rules, there needs to be a special room with the right tools and people to do tests.

5. The way the shoes are packed and labeled also has to follow the rules.

6. Each shoe sole must have its size, a number that shows when it was made, and the name of the company that made it on the label.

7. If one wants to put a special mark on the shoes (called an ISI Mark), the company has to get permission from the Bureau of Indian Standards.
