use the correct terms for shoe construction.
I have already have some ideas about this topic.
1,change the material to a more durable nano material—waterproof, stain proof, and anti-bacteria?don’t need to clean very often.
2. Change rubber insole to memory foam–support all types of feet, release the pain from long time walking of standing.
3. change outsole to a more soft material, improving shock absorption, breathable.
paper needs to be five paragraph…
