Boot Stretcher

I have a new pair of high leather boots, knee and they are a bit tight around the calves. Is it possible that I can stretch the tree a little without having to endure the pain of breaking them? And I'm worried when I take them off they'll go right back to where they started? Any suggestions?

go to a shoe repair shop. they can usually do it for you for less than $ 10 for the pair. This way you do not need to buy the stretcher and start so they can customize where to find them tight.
