I purchased one that I think is made out of plastic (http://www.amazon.com/gp/product/B00ZYOPTGM?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00) Hopefully you will be able to view the link. After looking through Amazon, I ended up picking this one, even though this is for men.Thanks for the idea! Did you just get one of those wooden shoe stretcher things or something more specific?
I just slowly stretched it over a few days per shoe.
