The "Synergy Custom" orthotic is our premium, custom made golf orthoses. This orthotic is fully customised, with the measurements and evaluations made off a scan, cast or impression of your own feet, making it the most accurate and "true fit" of the orthotic range. The Synergy Custom is best suited for professionals, frequent golfers, or golfers who may be experiencing a specific condition, such as plantarfasciitis, as it will generally produce faster results. If you are experiencing any pain, please advise us in an email upon ordering.
