So I took a chance on an indiegogo campaign and purchased these compression sleeves from spryngme.com.

Spryng claims to decrease the recovery time for calf muscles after exercise.

SPRYNG™ contains an innovative, patent-pending WaveTech® graduated compression pattern that prevents leg swelling and improves blood circulation. It does this by mimicking the skeletal muscle pump that occurs following strenuous exercise, aiding in the return of blood to the heart so swelling and muscle injury is reduced.

So what you get is a pair of one-size-fits-all pair of active compression sleeves, carrying bag and charger.

The dimensions of the bag with sleeves and the charger is about 14 x 7 x 4 inches, so this can fit in a backpack and easily into carryon luggage.

Each sleeve is labeled either right or left and is placed on the top of the foot and attached by velcro on the back of the leg. At first I had some difficulty putting on the sleeves because I have thick calves and didn’t realize that I was wearing the sleeves too high (I did contact customer support and they did notify me that they would be shipping out extensions for those of us who are well endowed).

Operating time after charging (about two to three hours), is about 15 minutes with up to 10 cycles of use between charges. The sleeves are turned on by holding down the center diamond button until the LED indicators come on. They are turned off by holding down the same button. The arrow up button is used for adjusting pressure and the double diamond button is for adjusting the compression pattern.

What makes this product unique is that it is active compression mimicking the natural compression in your leg without being tethered. The sleeves can be worn with or without clothes and you can even walk around while using them. However, they are not meant to be used while being active (only for recovery ) and not to be immersed in water.

I have used them for over a month now, two cycles after coming home from practices (and after a shower) and I can say my legs feel much better the next day and I have not had any muscle spasms (Charley-horses) waking me up in the night since then. They are easy to clean since the material is nylon and the inner liner which is attached by velcro to the sleeve is washable.

Some caveats. They aren’t cheap. The current price for a pair is about $250 in the US (includes shipping). It took me awhile to receive my sleeves mainly because they were having trouble with the FDA importing them into the US. I still have a couple warning letters from the FDA that I may or may not need to respond too (still waiting for spryng to respond but in a blog post prior to delivery, they had said I would not need to).

[Update: after back and forth with FDA, FedEx and spryng, FedEx finally agreed to take back the units so they could comply with the FDA. I received two BRAND NEW units, one of which was also quickly replaced for a malfunctioning sleeve with another brand new set. All of this without their knowledge I was reviewing their product. Kudos to you guys!]

Also, when first charging the units, the charging ports are really shallow. So don’t try to force the charging receptacles on the charging, they just barely hang there.

Pros:
Compact active compression sleeve that just works
Wireless
More or less one size fits all
Portable
Untethered

Cons:
Expensive
Took a long time to receive (warning letters from the FDA)
Charging port is shallow
May not fit as well for those with really thick calves (but extensions planned)

[Update: I received two sets of extensions free also. These also attach by Velcro.]

Price:
$249.99 USD (free shipping in US)
