I' did an achilles tendon lengthening(z plasty)because i had 6cm equinus problem.6 months after, i still feel my feet weak and my walking is bad. why?

Please consult : With your surgeon. With any tendon lengthening procedure there will be some degree of weakness. This is inherent in the procedure. Muscle/tendon strengthening may be helpful, a physical therapist can help with this, you may require orthotics or bracing in the meantime to prevent any falling or instability.

Muscular weakening.: When you have a muscle lengthened, you lose at least one grade of muscle strength. It can take up to a year before the muscle returns to 'somewhat' normal. You should be in therapy in order ro regain your muscle strength. Consult your podiatrist for exercises or go to a therapist.

Time: The achillis takes a long time to heal. Are you under the care of a physical therapist? Check back with the surgeon.
