Have been purchasing Propet products for 2 years now- Love them. Sturdy, comfortable and long lasting. Only grief I have had is the stitches coming loose in the toe area. Very stable  when walking. This particular style gets only 4 stars because the tongue seems to ride too high up on the top of the foot, rubbing a bit; annoying but not to the point of discomfort. Will continue to use Propet as my official work shoe.
