2XU is now producing Compression Calf Guards, in addition to their other compression items.  (IE: tights, shorts, short sleeve tops and long sleeve tops).  As you are aware, compression is becoming a very hot topic in the market - providing additional support to muscle groups, by reducing vibration - which ultimately delays the onset of fatigue.  It also is proven to be a wonderful recovery aid, by fascilitating the removal of the waste by-products the body produces during high active sport.  2XU combines our exclusive 50 denier lycra fabric with a revolutionary circular high knit gauge, the most compressive fabric on the market.  The extra push of blood from the outer extremities towards the heart allows a greater level of performance.
