CastleFlexx Heat is the world's first heated stretch device with a premium LG Lithium rechargeable battery.

Heat raises tissue temperature to boost blood flow, relax muscles, and reduce stiffness.

Targets plantar fasciitis, ACL/knee recovery, tight calves, and tennis elbow.

Features contoured heel placement for better achilles support and larger handles for easier grip.

Heat activates in under 45 seconds by holding the power button. Auto-shuts off after 30 minutes.
