Raising a child can be an expensive proposition, especially in these tough economic times.  Buy them a pair of sneakers and the next day they’ve out grown them.  Not so says one inventor.  The INCHworm sneakers are perhaps the world’s first size adjustable sneakers.  With the push of a button and a slight pull, the INCHworms can be increased in half sizes up to 3 increments (two sizes per shoes).  On the sole of the sneaker is an indicator which shows you the size and shouldn’t break, or at least so says the maker.  At about $70 a piece their not cheap (or good looking), but since they should negate the purchase of one pair there should some savings in the long term.
