Compression varies along the length of the stocking. The most compression is lower on the stocking. The compression decreases as it goes up the leg. You will need to be fitted for the stocking. The pharmacy staff will take measurements of various parts of your leg and foot.
Compression stockings come in closed toe or open toe styles.
During hot weather open-toe are cooler but the hem may become too tight after wearing for a period of time. If you find your toes swelling up below the compression stocking, take the stocking off and report this to your doctor. Compression stockings come in various lengths. The compression stockings that enclose the entire leg can be purchased with a waist belt. I personally like the style with the belt because it helps keep the stocking from sliding down the leg.
