Our Merino Runners, Merino Wool Knit, Wool Cross X and Merino Wool Boots can be machine washed on the “delicate” wool cycle, at a maximum of 30°C (90° F.)When washing, we recommend that you use a laundry net and a normal wool detergent. Don’t wash your Merino shoes together with other clothing items.Many machines use an intensive spin session at the end of the cycle in order to remove water from the items, but this should not be used when washing boiled wool. Instead, make sure that this setting is turned off on your machine, and gently press the water out of your shoes (for example, with a dry towel.) When caring for your Merino Runners, remember not to use any artificial drying methods: they should be air dried. Please do not put your Merino shoes into the dryer. Remember that when your shoes are lightly soiled that they can be cleaned with the simple use of a damp towel or gentle brush. If you choose to use a waterproofing spray on your Merino shoes, please ensure that the spray is designed for breathable materials. Here you can find some further tips and a step-by-step guide to washing your Merino wool.
