I have a pair of nylon over rubber boot foot waders that has an anoying (and cool) leak in one foot. I can't seem to pinpoint the source of the leak, other than that it may be in the area of the seam along the side or the area where the boot is bonded to the leg. Any repair ideas? or should I just get another pair? These ones are mabe 8 years old and have seen moderate use, mostly earlier in their life. I've used them less than 3 times in the past three years, so I don't want to invest much into a new pair. Thanks for your help.
