Question 1

How do I choose the right size, and will these make my shoes feel tight?**

Accepted Answer

The sizes correspond to general EU shoe sizes. Most reviewers find them true to size, but they do add a bit of volume. If your shoes are already a snug fit, you might want to size up your footwear or be prepared to remove your existing insoles. For a perfect fit in smaller shoes, you can easily trim them with scissors—just follow the outline of your old insole.

Question 2

Do they slip around inside the shoe?**

Accepted Answer

This is a common point mentioned in reviews. The insoles can sometimes slip forward when you remove your foot, especially in boots with a smooth interior. To prevent this, many users recommend ensuring your shoe is clean and dry before inserting them, or adding a few small dots of double-sided tape to the foam backing for a secure hold. They work best in footwear that already has a bit of a grip on the interior.

Question 3

Are these insoles suitable for very wet conditions or do they provide arch support?**

Accepted Answer

It's important to note their primary design is for *thermal* insulation, not moisture-wicking or orthopedic support. The soft wool top can retain moisture if your feet sweat heavily or in slushy conditions. Also, they are flat insoles. If you need significant arch support, you would place your existing orthotics on top of these thermal insoles for combined warmth and correction.

Question 4

How long do they typically last, and can I wash them?**

Accepted Answer

Based on user experiences, durability depends on use. For occasional winter wear, they can last several seasons. With daily heavy use, the foam may compress over time. We do not recommend machine washing. To clean, gently hand-wash the wool top with a mild detergent and air dry flat away from direct heat, which helps maintain their shape and insulating properties.

Question 5

Who would benefit most from these thermal insoles?**

Accepted Answer

They are a fantastic, affordable solution for anyone who needs extra warmth in cold, dry weather. TikTok and Reddit users especially love them for activities like winter dog walking, standing at outdoor events, or adding an extra layer of coziness to winter boots. They're ideal if your priority is simple, effective warmth rather than advanced moisture management or structural support.
