Tom:
Had my Aqua Stealths for a year+ and can't honestly say they stretched at all. I am impressed for wading flats or on rocks, but the hi-tech bottom in a slick trout stream isn't great and I use my old Borger's with felt. The good news is that Bean's will take them back no questions asked. Seems like you are in between sizes and the Aqua Stealth may not do it. One man's opinion is they are ok for some situations, but not the end all as advertised. Which is often the case whoever is the manufacturer. Hope this helps
