How long does it take to have newly made orthotics adjusted to your feet for treatment of plantar fasciitis?
Break them in. . Ask for specific directions from the doctor or professional who prescribed or made them for you, but the general rule is that you want to gradually increase your wear-time from 1 hour to a full day over the course of a week.
If your asking how . Long to fabricate new orthotics, roughly 2 weeks, if your asking how long for you to adjust or get used to wearing new devices, then i'd say couple of weeks.
Should be quick. Orthotics are for comfort and should feel better soon after getting them. Orthotics alone will not cure plantar fascitis. Stretching is the key.
