COOL* YOURBOOTS has been developed for swift cool-down of the muscles after exercising as well as for easy therapy in connection with minor injuries. Can be used in your YOURBOOTS or as a cold compression. INSTRUCTIONS: Put your COOL* YOURBOOTS in the freezer for a minimum of 1-2 hours. In the freezer, always make sure to keep your COOL* YOURBOOTS in the protective plastic bag. Remove your COOL* YOURBOOTS from the freezer and the protective bag, and it’s ready for use. Put on your COOL* YOURBOOTS where needed, and next put on YOURBOOTS (can also be used without air compression) The gel in COOL* YOURBOOTS is soft and flexible, even after many hours in the freezer. NEVER let your COOL* YOURBOOTS get wet. Ordinary sweat and condensation will disappear when you leave COOL* YOURBOOTS to air-dry on a towel after use. Pack your COOL* YOURBOOTS in their protective bag when entirely dry, and then – to make them ready for use again – put them back into the freezer. Do not use any fabric under your COOL*YOURBOOTS. The special gel and the thin neoprene will look after your skin.
