How long will it take if I want heated insoles sample?

It depends on our inventory and your requirements. If we have heated insoles you require in stock, we can send it to you right away. But if the sample you require needs some modification or customization, it takes more time to newly design, produce, and test. No matter it is for the standard sample or custom sample, we welcome your consultation. Tell us what you require, we anticipate how much time we need and then give you an accurate delivery time.
