I have worn Haflinger slippers for years now. They are my indoor shoes and I wear them at all times when walking on hard flooring. The ones with the felt bottoms, like the ones here and many other styles, are my favorites. This style is so very comfortable, supportive and has some arch support, but it's not too hard and flat or too soft and squishy.  The downside to this slip is that it will stretch out some, so I tend to buy them on sale a couple times a year.
