Very narrow and just before long walk, yet I have to tighten the tab to death for not lose. And it smells strongly of plastic, my late afternoon Socks have to keep the smell and they were wet, unlike my SHAYNA comfortable and airy hyper CROCS but a bit too open in cold and rainy weather. What a disappointment? It should also give the width of the feet to the waist or at least indicated for walking purposes !!!
