I own a very expensive pair of leather shoes that got horribly soiled.  I had no idea how to get them clean, so I hosed them off outside and used a bit of laundry soap to clean them thoroughly.  Then I put them in my laundry room to dry.  I checked on them periodically and began to get worried when I saw them shrink up and the sole curving drastically.  I thought I ruined my expensive leather shoes!  HOWEVER, I found this shoe stretcher on-line.  After checking around and reading reviews, I knew I would need something really heavy duty to stretch out the damage I had created.  There is only one stretcher and so you can only work on one shoe at a time.  There are snap on plastic buttons so that you can allow for specific toes that might get pinched.  The instructions are clear and indicated water saturation of the shoe to allow the leather to stretch correctly and to minimize any damage that could be caused by the stretching.  In just a few days, my shoes are stretched out to their original size and shape and fit great.  My only dilemma was the size of the stretcher I ordered.  I wear a size 10 and so ordered a large-it was almost too big but I got it to work. This shoe stretcher is heavy duty with only strong metal and wood parts.  Very well made and I highly recommend it.
