I can find anything on these questions I need to answer to pass year nine. My teacher said he doesn't matter where the answers come from as long as I pass and don't have to repeat.

PLEASE HELP ME! Due tomorrow!

1. List 5 latest developments in sports footwear. Describe how 2 developments help athlete performance in detail.

The sort of things that come to mind are lightness or low density, flexibility (modern plastics), breathable materials, strength (some use kevlar), cushioning (again modern plastics), resistance to wear, resistance to rotting (stability of materials), grip (changes in sole patterns) and designs of shoes for specific events.

You will have to choose two to describe in detail.
