I have these and what I did was to stuff the toe cap area with newspapers. Make sure that the newspapers are packed tightly and push them in as far as you can go. Change the papers once every few days.
And then wear the shoes for 1 day and give it a rest for the next, keeping it stuffed with newspapers.
I also apply this product called Foot Glide on my feet. This is a god-send! Stockings, moisturisers, vaseline...nothing ever worked for me. My friends always tease me about my `having Empress`s feet that requires a daily milk bath!`
So this Foot Glide producty is really up there on my `greatest invention-ever list`. You should be able to get this in drugstores or the shoe or sports section of department stores.
