Frequently Asked Questions
What size insole do I buy for my athletic shoes?
Refer to our sizing guide if you know your shoe size. If you are unsure of your shoe size use the measuring guide to select the correct Cluffy insole size. Please refer to our sizing guide for detailed measurements.
How do I install the Cluffy Insoles into my athletic shoes?
Remove the existing foam liner from your shoes and replace it with the Cluffy insole. View our installation video for a step-by-step guide.
Is there a break in period with the insoles?
No, the insoles can be worn all day on day one. Your body may feel different initially as you wear these. Your foot will start to move normally, and your balance will improve. Sometimes you may experience some temporary aches because you are using your muscles and tendons in a new way.
How often should I wear the insoles?
We recommend you wear these in your regular shoes as well as your athletic shoes. The Cluffy insoles will promote normal foot movement and improve your comfort, balance, strength and agility with athletic or everyday activities.
Can I move the insoles from shoe to shoe?
We recommend you keep the insoles in your athletic shoes and get additional pairs for your everyday shoes.
Can the Cluffy insoles get wet?
Yes, the Cluffy insole is made of a dense and durable closed cell foam that will not absorb water when immersed. The top cover fabric will dry quickly once set out to air dry. With repeated water immersion, the top cover may tend to separate from the foam, requiring more frequent replacement.
How do I clean the insoles?
The insoles can be washed in the regular wash cycle. Let them air dry, do not put them in the dryer. The foam will not absorb any water and the top cover will dry quickly.
What do I do if the insoles start to smell?
Make sure they air-dry between use. Spray the insoles with Lysol Disinfectant spray if the problem persists. Air dry thoroughly.
Do you have a product guarantee?
Yes! Our insoles have a 100% satisfaction money-back guarantee. If you are not satisfied, return the insoles within 90 days and we will provide a refund of your purchase price.
