I previously owned a pair of leather Merrill clogs. Perfect fit and smooth interior. Although these New Balance "sneakers" ( same idea as clogs) fit well enough, they are not very comfortable. Like many other sport shoe makers, New Balance designers spent far more time stitching together multiple pieces of leather (etc.) than making the shoe comfortabe. The resulting ridges, welts and sundry lumps in the interior of the shoe rub the foot in such a way as to create blisters. Not a good thing!
