Outdoor Hiking Boots

I have the dreaded black toenail syndrome after about four miles of hiking boots with my years. One salesperson in a store outdoor told me my boots are probably too short for my feet, even if the larger size let my heels too move. How can I do to stretch my boots fit properly, or is it still possible?

Are they leather? If yes, then you can buy a shoe: http://www.google.com/products?hl=en&sou ...

You can also get them at any shoemaker. If they are not leather, so you will not be able to stretch them. `I personally go with another boot.

If they are a "man" material you're unlucky.
If they are leather, they can sometimes be a bit tense. Contact a shoe repair the problem.

If the larger size is a little big, wear two pairs of socks!

You have to buy boots that fit properly.
