Bought these on the recommendation of my physio as I have a bad back. These replicate the same action is press your fingers into a tense muscle to get ride of the lactic acid and let blood into the muscle aiding repair. Have used them a few times and they do seem to work - but boy it can be painful sometimes!!
Great dress. Lovely material. I wear a size 14 and took the advice of other reviewers and orders a size 16 which fits perfectly. Can't wait to wear it!! Also looks even better with the red net petticoat I bought to go with it.
