Shoe And Boot Stretchers Can I Use Shoe Stretchers On Shoes With Rubber Soles?

Can I use shoe stretchers on shoes with rubber soles? - shoe and boot stretchers

Be shoe stretchers are effective when used with leather soles of shoes and boots, but I have a pair of sneakers that I love a little longer. If you use a shoe stretcher would have the rubber soles on the same track to stop and only reach the top of the skin, leaving me with a pair of shoes and deformed or destroyed by the desired effect of both rubber and leather?
