Possible Solution #2 Radio shoes- make
ordinary shoes more fun with radio that turns on when one walks

Possible Solution #3
Muscle Wire Shoes- Laces made with muscle wire and tighten when electric current sent through them. Hooks would hold shoe closed after contraction.
Pros and Cons (rated 1-5) 5=best 1=worst
Safety – 4 Long lasting- 3 (reusable yet might
need to be replaced over time) Original- 5 Helpful – 5 Size – 5 Affordable- 5 Possible to build?- 3
Possible Idea #4
Automatically zippering shoes- use a pully system zip and unzip shoes

Possible Solution #10 Electromagnets hold shoe
together – Electromagnets on either side of the shoe are turned on to pull shoe tight
Problems-Very strong electromagnets would be neededWould require much battery power.
