Pretty sure we are all faced with the fragrance of "low tide" wafting from our wading shoes, especially this time of year. Sometimes, simply rinsing them out and letting them dry does just not do the job. When that occurs, try rinsing them off, then placing them in a bucket of suds made with Dawn Dishwashing Soap and letting them soak overnight. Rinse, air dry outside and you may be amazed at the result.
This has nothing to do with catching more fish, but it might make life a touch more pleasant.
