Slim Walk Quick Reset Socks Beautiful Leg Compression Room Socks and Compression Spats Set There are pea cushions between the toes and on the arch of the foot, which open the toes and stimulate the arch of the foot with every step, improving blood circulation (the arch cushion has a non-slip grip). Furthermore, the high-compression design tightens the calves. I purchased these last year during the late stages of my pregnancy. I used the spats 2-3 times and the socks for about a month. I no longer plan to use them, so I would like to give them to someone who needs them.
