this product, now a bit cheaper than when i purchased it, is constructed with real wood and steel: the only plastic bits are the 'add-on' inserts--to meet individualized stretching needs--, and the handle that cranks the metal shaft. the device is so study, and so worth the money. if you're the type that regularly needs a significant break-in period for most shoes, or if your feet don't match the 'standard' foot in size or shape that shoes are designed for (whatever that might be), i strongly recommend that you invest in a quality stretcher, like this one. i have already used it on 4 pairs or shoes, and am wholly satisfied with the results. what a difference it has made in the comfort of my feet. and because this stretcher is so well-made, i am sure it will last all of my days. i have even lent it to my friend, since it works for several sizes. excellent product, the best offered on amazon.
