At Voegele Shoes the customer is taking center stage. Therefore we are proud to have integrated ShoeSize.Me in our online shop since February 2015. The Size Advisor helps our customers to find their perfect shoe size with only a few clicks. It has helped prevent multiple size orders, and the subsequent hassle involved of having to return the wrong pair. The boost in customer satisfaction shows also in fewer returns and an increased conversion rate. The project with ShoeSize.Me has been a great success..

The ShoeSize.Me Size Advisor helps our customers to buy with more confidence. The reduced return rate alone was able to generate significant additional value every month for La Redoute. Moving forward, we are going to actively promote the usage of the Size Advisor to all of our customers.

We realized that lots of potential customers refrain from buying shoes because they don’t know which size to choose. The Size Advisor gives our customers the necessary confidence in sizing to go through with the purchase. This results in an increase in our conversion rate.
