With every possible section zippered with wather proof zippers and a serigated sole; you could have any shoe like a sneaker fold into itself to a square of about four inches in total. This way you can wear shoes for weather appropriateness then pull out you comfortable fold aways for the destination or work place. You can't work in an office in boots!

Reward: A great hikers gift for you!

Wouldn't the shoe loose all of its support? I think beach shoes come as close as one can get. The sole is solid but the rest of the shoe conforms to your foot, making it easily compact able.
