Wouldn't it be neat if adjustable sneakers existed? This would be great, because our feet tend to be smaller during the morning hours; but enlarge around noon time. Therefore, the sneakers would be one size to accommodate our feet earlier in the day and then, stretch a bit to another size for the later hours of the day; and back to a smaller size for the following morning. Furthermore, this type of sneaker would be terrific since we wouldn't have to toss them out when our feet grow a half-inch to an inch bigger.
