Felt slipper of 100% pure sheep wool with a sole of soft calfskin. The slipper is flexible and easy to jump into. It keeps the foot warm and dry. How to take care of your glerups? 1. Since wool has an ability to self-clean, your glerups will stay fresh if you simply air them out and allow them to rest. 2. To remove stains we suggest that you gently clean on the stain with at light wet cloth and wool soap. You may have to repeat the process a few times, but make sure that you always leave the slippers to dry before starting over again. 3. Vacuum or blow your glerups clean of dust. Leather soles can be brushed and cleaned with a leather brush. 4. Please be careful – rubber or leather soles may be slippery on wet and icy surfaces such as tile. 5. All our uppers are produced in 100% pure wool and therefore you may experience colour difference from batch to batch. 6. Your glerups usually shed within the first 3-4 weeks of wear giving you a long-lasting comfortable feel for years to come. This is normal due to the treatment of our wool. Simply remove the shedding fibers and discard as desired.
