“E-size” is an online assistant for selecting shoe sizes. This product is created for online shoe stores. Almost one in five pairs of shoes sold online are returned due to the wrong size. The service allows you to reduce returns due to incorrectly chosen sizes and increase customer confidence. We integrate into an online store = the client does not go to third-party services, does not open other people’s links = he remains on the product page on your website = does not abandon the cart, but continues shopping already knowing the exact size.
