After many years of use my waders finally sprung a small leak. It is somewhere in the right bootfoot area. First I thought it was around the sole - applied sealant - no luck. Then I thought it was higher up, where the bootfoot meets the wader, also no luck. Do you have any good tricks/tips on how to find where the leak might be?

It is a slow leak, after a 1/2 day of fishing I just end up with a wet sock - I can still fish but I would like to take care of it.

Thanks in advance,

Alberto
