These shoes are incredibly comfortable. I was having heel pain/planter fasciitis I tried several different shoes before these. Since wearing Skechers work clogs  (40+ hours a week)  I have not had any problems. When I 1st started wearing them I felt like I was walking on a trampoline, they are wonderful. HOWEVER they run large I ended up with a shoe an entire size smaller and they keep getting larger. They are a clog so they are not fitted in the heel however the entire shoe is stretching to the point I can not keep my foot in them with out effort. I have 2 co-workers ( between the 3 of us we have sizes (7, 7.5 and 8) who purchased the same shoe and they have the same experience. I have had mine now for 4 months, I am on my feet  at least 6 hours a day walking, lifting and some standing, they are still in good condition, very comfortable. I will purchase another pair but will go even smaller next time.  One other note is the 1st few days of wearing the shoes there does seem to be calf soreness but it goes away after you adjust to the shoe (maybe its due to heel height).
