Yes! ThermaBoots are true to size. Simply refer to our sizing chart and choose your normal UK shoe size for the perfect fit.

Will you restock sold out sizes?

We restock popular sizes as quickly as possible, but due to high demand, we cannot guarantee availability. If your size is sold out, we recommend checking back regularly or signing up for restock notifications on the product page.

Are they really 100% waterproof?

Absolutely. ThermaBoots feature fully sealed construction that keeps your feet completely dry in rain, snow, puddles, and slush. Walk with confidence in any wet conditions.

Can I wear them without socks?

Yes! Many customers love wearing ThermaBoots without socks thanks to the thick, plush fleece lining. The interior is so soft and comfortable that socks become optional.

Are they suitable for both men and women?

Yes! ThermaBoots feature a unisex design that works perfectly for both men and women. Simply choose your size from our sizing chart.

How do I put them on?

ThermaBoots feature an easy slip-on design with a side zip for a secure fit. Just slide your foot in and zip up the side – you're ready to go in 3 seconds. No bending down to tie laces.

Are they heavy?

Not at all! Despite being fully waterproof with fleece lining, ThermaBoots are surprisingly lightweight. They won't tire your legs out, even after a full day of wear.

Will they keep my feet warm in winter?

Yes! The thick fleece lining is specifically designed to keep your feet warm and cozy in cold temperatures. Perfect for winter walks, commutes, and outdoor activities.
