You can machine wash your Atoms on delicate (slow cycle, cold water only).
For best results, take the insoles out, keep the laces tied, put your Atoms in a linen bag or pillow case, and mix in towels or sheets to pad the washing machine. DO NOT MACHINE DRY. The custom foam midsole will distort its shape in the dryer. Please air dry with inserts or shoe trees out of direct sunlight.
We don't recommend you do this often, but understand a deep clean is needed sometimes.
