Slippers
Our slippers are cut according to the usual shoe sizes. Please order slippers according to your normal shoe size. If you already own a matching Giesswein slipper, please order according to this size. Please note that boiled wool slippers will expand slightly over time.
How do I measure correctly?
Take a piece of paper and a pen. Step on the sheet of paper with your foot and mark the heel and tip of your toe with your pen. Do the same with the second foot. Feet are rarely exactly the same length. If you already know the longer foot, it is sufficient to measure its length. Determine length in cm. Please use the ruler to determine the length in cm. The tables below translate the sole length into all common sizes.

ULTRALIGHT SOLE
WITH ALGAE BIOMASS
The advanced performance sole is made from EVA material and rapidly renewable algae biomass. This combination gives the sole a feather-light weight while ensuring a more sustainable production.

SUPER FLEXIBLE UPPER
MADE FROM RECYCLED PET
The unique upper is knitted from a high-performance yarn made from recycled PET plastic. This not only reduces environmental impact, but also reuses valuable plastic.

RESOURCE CONSERVING
Harvesting fast-growing algae supports the regeneration of water bodies. By managing the growth of algae, they are prevented from over-exploiting the waters and depriving them of oxygen.

CLIMATE-FRIENDLY PROCESSES
Recycled plastic is returned to the production cycle to ensure sustainable reuse. This gives the plastic waste used a second life and helps reduce environmental impact.
