Contrary to all fears that rubber boots are first class! Unlike other rubber boots Crocs Wellies are made of a kind Schaummstoff and not sticky from the usual rubber. So you can fine pure rise even with trousers without that the pants is pushed up to the knee and is much easier these wellies are also. Running is very comfortable in the shoes, even if they at first have to be broken in some (because they are relatively stiff in the beginning).
