Introducing the Precise Insole Collection!

Vancouver, Washington: Amfit, Inc. announces the release of the Precise Insole Collection which includes both custom and off-the-shelf options. Utilizing foot data gathered from over 30+ years in the medical industry we have developed the best fitting performance insoles in the industry. A customer has the opportunity to create a custom insole with either our Precise LT or Precise FP, or our off-the-shelf option, the Precise SP. The Precise LT uses our patented Contact Digitizer for 3D digital casting and design of custom foot orthotics with a quick 48 hour turnaround time. The Precise FP, or FootPrinter, is a DIY, foam casting system that creates a 3D profile of the foot that is scanned and the data gathered to also create a custom insole. The foot soldier of the group is the Precise SP (Stability Platform) which is an off-the-shelf solution that provides the underfoot stability feet crave. So whether it’s custom, or on-the-go, Amfit has people’s feet covered. Best of all, all of our products are designed, and built in the USA!
