Notes from our Certified Fitters:
Always contact your physician and or therapist to determine the correct compression strength for your condition. Activa hose should be replaced after six months of normal wear. They start losing their effectiveness after that time. If they seem to be getting looser, than you are not receiving the maximum benefits of their compression strength.

Activa Compression Legwear is one of the most complete and innovative product lines available with a range of styles, colors, and compression levels to fit many lifestyles and needs. Premium, modern materials are combined with proven designs for ultimate form and comfort.

Activa® CoolMax® Athletic Support Socks provide graduated compression that improves circulation, relieves leg fatigue, and prevents calf muscle cramping and ankle / foot swelling. Graduated Compression occurs when the pressure is greatest at the ankle and sequentially less up the leg which provides the greatest therapeutic effectiveness for reducing leg symptoms.

CoolMax® is a performance fabric that includes an effective fiber-based moisture management system that can move perspiration away from the body and through fabric where it can evaporate quickly, allowing the wearer to feel cooler and more comfortable.

Care Instructions:

For Hosiery Stockings: Hand wash in warm water with mild soap. If hosiery is extremely stretched out after wear, washing in slightly warmer water may return them to original shape.

For Compression Socks: Hand or machine wash in warm water with mild soap.

For all compression garments:

  • Do not Bleach.
  • Blot to remove excess water.
  • Air dry away from heat.
  • Use of a laundry bag helps to protect the garment during washing.

See package insert for further information and instructions.

Sigvaris, Jobst, Juzo, and Mediven make special Washing Solutions specially designed to help maintain the quality of compression garments and extend their life.

Measuring for Compression Stockings:

It is recommended that you mark the leg with a non-permanent, non-toxic marker at each circumference measurement made.

Measurements should always be taken as soon as possible after waking when swelling is minimum

Measure next to bare skin

The measuring system is based on having the foot flat against the floor

Measurements must be taken by pulling the tape snugly around the leg but without constriction

Measurements should be taken from the ground up

About Leg Health:

Many factors contribute to the overall health of our legs: heredity, weight, age, diet and activity level. But it's the internal function of the legs that also plays an important role: calf muscles, arteries, veins, and vein valves-the internal highway of blood and oxygen flow.

Your Circulation:
The flow of blood in the veins is assisted by a series of one-way valves. The valves remain open when the blood flows toward the heart, and then closed after blood passes through. Over time, an increase in pressure can stretch the vein walls. If a vein becomes enlarged and over-stretched the valves cannot close properly, causing blood to leak back down into the lower legs, resulting in poor circulation.

If this happens you may begin to develop symptoms, such as:

  • Heavy, tired, aching legs
  • Swollen legs and/or ankles
  • Sensation of warmth in the legs
  • Tingling or cramping of the legs
  • Dull or sharp pain in the calf
  • Small varicose veins and spider veins

Using Compression Therapy:
Graduated compression means the pressure is greatest at the ankle and sequentially less up the leg. Since this is the most effective for reducing leg symptoms, graduated compression stockings and socks are important to leg health. They help minimize muscle aches, swelling, and symptoms of fatigue. Exercise and a healthy lifestyle will strengthen your legs, but wearing graduated compression stockings or socks will support the internal function of the veins.

Activa® Compression Legwear is a high quality, innovative line of compression stockings and socks available in a range of styles, colors, and compression levels for many lifestyles for men and women.

Midtown Health offers many brands and types of athletic and active-wear socks. Please browse our Athletic Section for unique selections.

Our Certified Fitters recommend that donning gloves always be worn when applying your compression garments. These gloves have a gripping texture that makes it considerably easier to put on compression hose. Donning gloves also help to prevent tearing, snagging or putting a nail or finger through the garment. This is especially true with the sheer compression hosiery.

Midtown Health offers a large selection of Donning Gloves and other donning aids in our Compression Accessories section, including the Juzo Slippie Gator, Sigvaris Extensors, and Mediven Butler, all designed to assist the pulling on and removal of compression stockings.

We also recommend either Sigvaris, Juzo, or Jobst Jolastic Special Washing Solutions for maintaining the quality of compression garments. Jobst Jolastic Wash is formulated to remove oil, body acids, and skin salts quickly and easily without damage to the fabric. This specially designed solution will help extend the life of all elastic garments. The ingredients in Jobst ensure excellent soil removal and are mild to the user's hands.

Many of our customers love Alps Fitting lotion. ALPS 100% Silicone Fitting Lotion Skin Conditioner for Sensitive Skin leaves a smooth, silky feel to sensitive skin that is chapped and dry. When used before putting on stockings, ALPS fitting lotion helps prevent snags and facilitates donning of compression garments.

You will find other useful products in our Compression Accessories department, including compression bandages, adhesives, pads, donning devices, and detergents.
