After reading the reviews on this shoe I was a bit reluctant to order but I had to check out this product due to a foot injury. Normally, I wear Clarks for business shoes with an orthodic inside.  Most reviews stated a small toe box and slipping in the heel, I did not experience either, I ordered a medium and my normal shoe size and a great fit. I have really high arches and this shoe has a great built in orthodic.  However the quality of the material, I thought stated leather for this shoe - however leather it is not.  Great comfort but very disappointed in material of shoe quality.
