I have owned a half dozen or more pairs of Keen hiking shoes. FITFLOP: PLEASE GO BACK TO THE WAY YOU USED TO MAKE YOUR SHOES. Dell Inspiron 9571 i5 9th Gen 8GB Hynix DDR4 RamPurchased 2x8GB of HyperX Impact. I almost sent them back because they werent recording properly and I was getting a great deal of feedback. Not the most comfortable shower/house-wear flops if you intend to wear them around the house. That?s probably why there is such a difference in size and material.
