That is a pretty accurate assessment...they are a more cheaply crafted version of the clogs they sell at retail outlets. The material is both thin and overly stiff, the seams appear to be glued rather than stitched, and the sizes are off by one. I wear size 13's wit every shoe except English sized footware like Doc Martins, which i wear a 12.5...these 13's were more like 14.5's...waaaayyyyy too big!
Dont bother with these clogs. For an extra $20, you can find quality clogs that will last a couple years.
