The models with 1.X in their name (ie 1.1a, 1.1b, 1.1c, 1.1d, 1.2a, etc):

For these models, if you hesitate between 2 sizes, we recommend you to take half a size or a full size bigger than normally
To maximize your comfort, all our sneakers come with a thick leather covered memory foam internal sole.  This reduces somewhat the room inside the sneaker explaining why it could be better to take half a size or a full size bigger than normally

 

All other models (i.e the models with 2.X, 3.X, 4.X 5.X or 6.X in their name):

Our other models fit true to size.  Take therefor the same size as you would normally take

These models also come with the same thick leather covered memory foam internal sole as the 1.X models, but we have used a slightly wider last to compensate for the space taken by our special sole
