Hello tendon3?,
Unfortunately, we do not have a ColdCure device that would work for treating both of those injuries simultaneously. To get an effective cold therapy on both injuries, you would need two different devices. Our Achilles ColdCure for Achilles tendonitis and a Foot ColdCure for plantar fasciitis.
One thing I might suggest that would be a bit unorthodox; if you purchased the Achilles wrap, you could possibly use it for your plantar fasciitis by simply laying it flat on the floor and placing the bottom of your foot on it. It would be a bit different, since the wrap won't be fitted to your foot like the Foot ColdCure would be, but if you're trying to save some money, that may be something to consider.
Feel free to call us at 844-400-2525, or email us at service@kingbrand.com, if you ever have any questions!
