Tulis FAQ's
1. What are Tuli’s Heavy Duty Heel Cups?
Tuli’s Heel Cups are shock-absorbing inserts designed to sit under your heel inside your shoes. The Heavy Duty version is thicker and provides extra cushioning for high-impact activity or long days on your feet.
2. What shoes do they fit into?
They fit most lace-up shoes including runners, school shoes, work shoes and everyday sneakers. They may feel too snug in very tight dress shoes.
What’s the difference between Classic and Heavy Duty?
Classic = standard thickness for everyday shoes.
Heavy Duty = roughly twice as thick, ideal for sport, high-impact activity and roomier footwear.
How long do they last?
They’re durable, reusable and designed for daily wear. Most people move them between different pairs of shoes.
