The heel is approximately 2 1/8" wide to keep you stable.
The Suede Sole is quite flexible and the heel has a synthetic bottom that won't slow you down when it touches the floor during a spin.
Want to dye these? We were told that ordinary fabric dye would work better on velvet than traditional shoe dye. So we bought fabric dye, took out the laces, taped the trim and sole and dabbed away. The result wasn't absolute perfection, but looks delicious. When we did a pair without taping the trim it just became a lighter version of the color of the velvet. The stitching does not take the dye well so it stands out nicely. (We have not tested these in the rain, so no guarantees on waterproofing).
ABOUT SUEDE SOLES:
These fit pretty true to size for women with Normal or Narrow width feet.
Women who've tried these on report that these are fitting either perfectly or a half size smaller than their street shoe size (i.e. if you normally fit 7.5 -to- 8 you'll probably wear an 8 and sometimes an 8.5 in these).
Second pair of this style? If you bought one of these when they first came out then there's a small chance that they won't fit exactly the same as your original pair.
