Will they fit my shoes?

Yes. The Pure slides underneath your existing insole, so it fits inside trainers, work shoes, hiking boots and everyday shoes.

How long until I feel a difference?

Most people feel the change on day one. Give your feet 1–2 weeks to fully adapt to proper support.

What if they are not for me?

Try them for 30 days. If they are not right, send them back for a full refund.

How to choose your size

The Pure is designed to fit true to size. Order the same EU size as the shoe you'll wear it in.

Between two sizes? Size down. If you normally wear a 42 or a 43, choose EU 42.

Worn by people who move.

“As I'm training for an triathlon I'm moving a lot. Especially during my runs fatigue would kick in fast. With the flexitec soles I can honestly say I'm fatiguing less during my runs. I'd buy it 3 more times, absolutely worth the money.”

Jesse T. · NL · 25 Sep 2026

“I've been using the SOLE insoles for a while now and I'm very satisfied. They give more support and stability without feeling hard. My shoes stay comfortable and my feet feel less tired. The insoles fit easily and feel high quality. Fast delivery and neatly packaged.”

Why The Pure is different

Ordinary insoles cushion. The Pure adds the patented spring steel core underneath — without replacing the insole you already trust.

Frequently asked questions

How do I choose my size?

Order your normal EU shoe size. Between sizes? Size down for the best fit — for example, if you wear a 42 or a 43, choose EU 42.

Can I move them between shoes?

Absolutely. Many customers buy two pairs so they never have to swap — but a single pair moves easily from shoe to shoe.

How is this different from a normal insole?

Ordinary insoles only cushion. The Pure adds a patented spring steel layer underneath your own insole — restoring arch mechanics and returning energy to every step, without changing the fit or feel you already love.

How long do they last?

The spring steel core is built to last for years of daily use without losing its support.

Do they help with joint or back pain?

By restoring natural arch mechanics, The Pure eases load on knees, hips and back. The spring-steel core holds its shape and returns energy with every step.

When will my order arrive?

Belgium, the Netherlands and Luxembourg: next business day when ordered before 15:00 (CET) on a business day. Germany, Austria and Switzerland: 1–2 business days. Rest of the EU: 3–5 business days. Shipping is free across Europe.
