Washing shipping boots

i’m new to using shipping boots, i’ve been an user of standing wraps forever

these boots got pretty gross/muddy on their first use and the label says they can be washed cold and not to be put in dryer, but that seems skeptical to me due to their material and shape

wondering how you all care for yours… thanks!!

I throw them in the washer on cold, prewash and extra rinse. Air dry.

I did mine on bulky, cold water, extra rinse. Air dry. Never had a problem. But make sure you close the velcro fasteners!
