By following the tips in this guide, you can ensure your shoe insoles stay clean, fresh, and supportive.

Taking good care of your insoles is key to maximizing their benefits and lifespan. Here are four simple yet effective ways to maintain your insoles:

• Wear Socks and Change Them Regularly. Socks absorb sweat, keeping insoles cleaner for longer. Make sure to change your socks daily or after activities that cause excessive sweating.
• Keep Insoles Dry. Thoroughly air dry your insoles and shoes after use to prevent bacteria growth and odor. If they get sweaty or wet, remove the insoles and air them out separately.
• Choose Breathable Insoles. Select insoles made of breathable materials to encourage air flow inside your shoes. This reduces sweat buildup and keeps your feet odor-free.  All Tread Labs insoles are made with breathable, long-lasting, open-cell polyurethane foam. Dash Insoles include ventilated foam top covers for extra breathability.
• Choose Anti-Odor Insoles.  Tread Labs insoles have top covers that are treated with a PURE™ silver ion treatment that will not wash out or degrade, and will keep your insoles fresher for longer.

Insoles, like other part of your shoes, have a lifespan and need replacing over time. But how do you know when it's time to get new ones? Let's break it down. 

• Flattened Support. The arch support has flattened or shows visible damage. 
• Visible Wear. Look for cracks, tears, or holes in the insole.
• Persistent Odor. If repeated cleaning doesn't remove the smell, it's time for new insoles.
• Color Changes. Significant discoloration can indicate material degradation.
• General Rule of Thumb. Typically, replace insoles every 6-12 months, depending on your activity level and usage.

• Two-Part System. Tread Labs insoles are constructed using a two-part system consisting of molded arch supports and replaceable top covers.
• Arch Support Guaranteed For Life. Tread Labs molded arch supports are unconditionally guaranteed for life under the Tread Labs Million Mile Guarantee.  This means the arch supports will not flatten, crack, or degrade.
• Replaceable Top Covers. Tread Labs top covers are easily replaceable at affordable prices when they wear out, extending the lifespan of the insoles and saving money.  Depending on use, Tread Labs top covers generally last a year or so.

Maintaining clean and well-cared-for insoles is key for lasting foot comfort and health. Regularly cleaning your insoles keeps your feet happy and extends the life of your insoles. Timely replacement of worn insoles ensure that your insoles stay effective and supportive in all your activities. Remember, taking a few moments to care for your insoles can make a significant difference in your daily comfort and foot support.
