Altering waders--big feet, normal leg length.

People with big feet, normal leg length and medium build have a problem.   I have waders in size 12 boot for my size 11.5 feet, but with legs about 3" longer than I need.  The "stout" size waders offered by some makers better matches normal leg length with big feet, but while also making the torso size about 8 inches greater than needed for a medium built body.

A brief web search shows that no one on the web has a method of altering these.  I thought briefly about cutting and re-gluing the legs, but a small gap in re-gluing would result in a leak.  The next solution:  fold down the neoprene pant leg on itself, and glue it down.

The process:

1. put on waders, stand up and fold down the amount of pant leg that makes them fit as desired.
2. Mark the bottom of the fold and the bottom section where the fold stops.  both lines should go all the way around the pant leg.
3. With a sharp knife, cut the fabric cover of the neoprene on the lines.
4. Carefully pull up on the fabric between the lines, leaving the neoprene exposed.
5. Apply contact cement ($5 at Home Depot) to the neoprene.  Do this is a well ventilated area.
6. Wait 10 minutes for the cement to get tacky.  
7. Press the neoprene together, matching the cut edges of the fabric neoprene cover.
8. Turn the pant leg inside out enough to expose the fold inside.  Cut away the fabric that touches and glue as in 5 and 6 above.

I'll soon know how this works.
