I ordered a pair of those soles about 2 weeks ago and cannot recommend them highly enough.
I have severe biomechanical problems due to scoliosis and only walk about in the house but I have become dependent on them as walking without them only leads to unnecessary and prolonged difficulties.
This order is for my mother who has a completely different set of problems but said she immediately felt the benefit when she tried mine for a short time.
Thank you very much.
