These slippers have a narrow sole, I felt my foot was not supported on either side. No Arch Support You can use a curved insole and still balance on a narrow sole. They look good, are well made and light weight.
Pros
Muy Comodo calzado, luce bien, creo que fue buena inversion.
Cons
All good except the insole sent together is 2 sizes too big... sticks out over the slipper... looks awkward.
