Inserts, insoles, and orthotics—three terms often used interchangeably but with distinct differences that can impact your foot health.

Foot Support 101: Comparing Inserts, Insoles & Orthotics

Are orthotics, insoles, and inserts all the same thing?

The short answer: mostly, yes.

Like many words in the English language, the differences often come down to regional preferences and how people use the terms. Much like "sneakers" in some areas might be called "tennis shoes" elsewhere, terms like orthotics, insoles, and inserts are often interchangeable.

However, there are some subtle distinctions worth exploring. So, while the terms orthotics, insoles, and inserts are often used to represent the same thing, the truth is they’re not entirely the same. Each serves a unique purpose, offering different levels of support, comfort, and functionality. Understanding these distinctions can help you make more informed choices when it comes to caring for your feet. 

To help clear up the confusion, let’s break down the terminology and what it means for your feet:

Comparison table highlighting the differences between insoles and orthotics. The table contrasts key aspects such as alternative names, purpose, customization level, duration of use, purchasing options, durability, and price.

Factory Liners or Sockliners

These are the thin layers of fabric or foam found inside your shoes when you first buy them. Factory liners, or sockliners, sit between your foot and the midsole of the shoe. Some are glued in place, while others are removable.

Footbeds

Shoemakers often use this term to describe the built-in cushioning inside your shoes. While “footbed” might sound like a cozy mattress for your feet, the term is also used for aftermarket insoles that offer shape and cushioning. In some cases, “footbed” refers to footwear like sandals with integrated arch support and padding.

Insoles vs. Shoe Inserts 

Insoles are pre-manufactured inserts that add comfort and light support to your footwear. They are a more accessible option for those looking to improve everyday foot comfort without addressing specific medical conditions. 

“Shoe insert” is another term for insoles. It typically refers to any aftermarket product that’s placed inside your shoe for additional comfort or support. Simply insert them into your footwear, and you’re good to go!

  • Purpose: Insoles provide extra cushioning, arch support, and shock absorption, making them ideal for general use or mild discomfort.
  • Materials: Typically made from gel, foam, or memory foam, with some models featuring semi-rigid support.

Customization: Limited—many insoles can be trimmed to fit your shoe size but are not tailored to your unique foot shape. The fit can be quite versatile though with some options available in full-length, three-quarter length, or specific designs for different footwear types.

Illustration of four types of partial shoe inserts: (1) Heel Lifts, which provide elevation under the heel, (2) Heel Cups, designed to cradle and support the heel, (3) Metatarsal Pads, which alleviate pressure on the ball of the foot, and (4) 2/3 Length Insoles, which offer additional support without covering the full footbed.

  • Durability: Designed for short to medium-term use, typically lasting 6-12 months with daily wear.
  • Cost: Affordable, usually ranging from $20-$90.

At FITPACE, we define insoles as aftermarket additions designed to enhance your shoe’s performance, comfort, and support. Unlike factory liners, our insoles are carefully engineered to improve alignment, reduce strain, and provide customized relief.

What Are Orthotics?

So, are orthotics and insoles also just two words for the same thing? Not exactly. 

While both provide support and comfort for your feet, they serve distinct purposes and are designed to address different needs. Orthotics, sometimes referred to as orthopedic insoles, are medical devices designed to treat specific foot conditions. They are either custom-made or pre-made but recommended by healthcare professionals.

  • Purpose: Orthotics address biomechanical issues like plantar fasciitis, overpronation, or metatarsalgia. They correct foot alignment, improve posture, and provide relief for chronic pain.
  • Durable Materials: Often made from a combination of rigid materials (like plastic or carbon fiber) and softer cushioning layers. Hence, they are intended for long-term use, lasting 1-5 years depending on the exact materials and usage.
  • Custom Fit: Highly tailored—custom orthotics are molded to fit your exact foot shape, ensuring precise support.
  • Cost: Higher investment, ranging from $400-$600, with some costs potentially covered.

Do You Need Orthotics or Insoles?

If you’re dealing with mild discomfort, fatigue, or simply want extra cushioning in your shoes, insoles like those from FITPACE are an excellent choice. They’re affordable, effective, and easy to use for most daily activities or athletic routines.

For chronic pain, recurring discomfort, or specific medical conditions, consulting a podiatrist for orthotics might be the better option. Orthotics offer a long-term, medically guided solution for correcting alignment and supporting weakened structures.
