HYPERICE NORMATEC Hyperice Normatec Leg Attachments A pair of replacement or additional leg attachments with overlapping zones for gapless compression, premium-grade locking zippers, and a foot section shaped to compress the sole without squeezing the toes. Hyperice recommends 20 to 60 minutes a session, typically 20 to 30. Three sizes — Short, Standard and Tall — all at one price, and no control unit included. Normatec sizes by inseam: under 31" is Short, 31" to 35" is Standard, over 35" is Tall, measured from just below the crotch to the bottom of the ankle. Size down if you fall between two. Buying the attachments on their own is the cheaper route when your boots have worn out but the control unit is still good, and it is also how you add a second pair for a partner or a clinic.
