Did you choose the correct shoe size?
Please remove the insoles from your shoes and stand on them. It is important that your heels are flush with the insoles. The marked PerfectFit area will tell you whether the size you have chosen is suitable.
The Vario-Fit insoles are compatible with some of our shoes. Simply search for the right insoles for your shoe model at Accessoires and go to "Select size". If there are different types of insoles, you can choose between narrow, normal and wide foot. If your shoes are too narrow for you, the yellow insoles are ideal for the wide foot.
Please feel free to contact our customer support team so that we can offer you personalised advice. You can reach us either via the chat function at the bottom right of the online shop or by phone on +49 (0) 8751 / 8625 888. As we use different lasts depending on the model, our shoes may vary in fit.

Are you looking for a specific model and can't find it in our webshop? It might be a special or discontinued model.
Would you like more information about this shoe? Please contact us:
The reason for this is that very large sizes are only infrequently requested by customers. This means that production costs are higher than for standard sizes. Production processes also need to be specially adjusted, for example, and material use is greater. Nevertheless, we wish to be able to continue to provide this particular service to our customers. We are, therefore, compelled to charge an oversize supplement for shoes which do not correspond to the usual sizes.
