I took a second chance and tried again. The box arrived. I didn't get my hopes up. I opened the box, pulled out one properly sized shoe then pulled out... another properly sized shoe for the opposite foot. Success!
Good thing because my knees and shins were starting to feel the effects of walking in shoes long past their useful life.
So now I'm off to take China for her beauty walk. I came across this video, and now I'm wondering if I can train her to do this for me.
Watch 'til the happy end!
