How do 3D-printed footwear designs most directly enhance performance?

  1. By providing lightweight, customised support for efficiency 
  2. By enabling variable density midsoles that optimise energy return
  3. By incorporating lattice structures that reduce manufacturing costs
  4. By regulating foot temperature in hot conditions

\(A\)

Show Worked Solution
  • A is correct: 3D-printed footwear is most effective when customised to an athlete’s biomechanics, offering lightweight support that enhances efficiency and reduces injury risk.

Other options:

  • B is incorrect: Variable density midsoles can aid energy return but this is a broader shoe design feature, not specific to 3D printing.
  • C is incorrect: Lower manufacturing costs are an economic benefit, not a direct performance improvement.
  • D is incorrect: Foot temperature regulation relates to smart textiles, not 3D-printed design.
