Has anyone had any success with this?
I took my new worker boots to the shoe repair man to get the instep stretched and he said his machine can't do boots! and suggested i try shoe stretcher spray then procceded to attempt to flog me a £10 can of the stuff! Luckily mum had some already at home.
How long does it take to stretch them? are we talking weeks of wear or a couple of hours? x

Edit- just it work just wearing them after spraying or is it best to get one of those shoe stretcher things? x
