Ok lets get this straight. YES these are leather but absolutely NOT HEAVY DUTY QUALITY LEATHER. If anything these feel like man made chinese leather. Sorry just calling it like it is.

  However these are very comfortable. I am new to the world of hurt feet and clogs but these feel really nice to me.

 SIZING ? I went nuts trying to figure it out. I am  a size 11.5 in most chinese made shoes today. After doing TONS of research I decided to go with a 46 listed at 12/12.5. They fit like an 11.5 chinese ! Confused yet ????? So am I but they wound up fitting well.

 Durability ? So/so only time will tell. I plan on using these around the house. If you take these outside they will definitely get more of a beating.  If so I would hedge that they would degrade before the year is up.
