My 2 and a half year old girl has my feet. By that I mean they're growing like she spends all day stood in fertilizer. So I had this GENIUS idea. What if shoes could grow as your child's feet grow? Well, someone beat me to it!

They're called INCHWORMs , they grow 3 sizes, and they've actually been around quite a while. I found articles on the web dating back to 2002, and I'm amazed they haven't caught on. They look great, they have a bunch of styles, and they're exceptionally well built.

The technology is relatively simple. An accordion-style center to the shoe gives it room to expand while keeping the shoe comfortable and well fitting. Simply press a button, pull and the shoe can grow from say a size 11, to an 11.5, to a 12. At $49.95 they're not cheap initially, but remember you're getting 3 shoe sizes for the price of 1. So, at less than $17 per size for a quality shoe, that's a bargain and no mistake.

If you're a parent, you'll know just how expensive shoes are for your kids. And how quickly they grow out of them. It's not easy to pay $40 for a pair of size 8 toddler shoes when you know in three months that they'll be going to Goodwill. Inchworm shoes can't stop that from happening eventually, but as they grow three sizes they can triple the amount of time you get between shoe shopping trips.

The video below shows the Inchworms in action. I'm going to go grab a few pairs from their online store before they really catch on and go up in price. The press has been heating up on these. But as a parent, it's great to see a genuinely clever, much needed product come along that saves us money. Huzzah!
