Inspection & Exchange Process
Please describe your warranty issue on the right and upload both a picture of the bottom and the top of your insoles, besides a close up of the manufacturing defect.
MASS4D® will promptly review your claim and notify you with our findings. If a warranty review is granted, a courier will collect your current insoles for inspection.
If a manufacturing defect is confirmed and warrants an exchange, a new pair of the same size and profile will be sent to you. MASS4D® will pay the shipping costs related to authorized warranty exchanges only.
