Ssh-oes are comfortable heels engineered to not make noise when you walk. Ssh-oes are padded with sound absorbing acoustic foam and have a non-slip rubber outsole. We also use a patented heel tip that absorbs sound and prevents against wear and tear so you do not have to get your heel tips replaced as often. Ssh-oes are also comfortable with a "blister-free" lycra lining that molds to the shape your foot for a customized fit.
