Our Sizing Chart It is not easy to buy shoes online. We want you to get the right size, the first time around. Many companies have sizing charts according to average age or just the sizes. The problem with them, is that every child is not average and sizing differs between companies. Our sizing chart is different, in that you select the size according to the length of the feet in inches. We have already built into the charts, extra length for comfort and growth. All you need to do is measure the feet and see where that measurement falls in the chart. For measuring instructions, visit http://www.pipsqueakers.com/SIZING-Charts_ep_29-1.html .
