I had DVT 21 years ago after giving birth to our second child. I have been wearing support hose 20-30 compression ever since. I am 57 yrs. young. Hiking, snow shoeing, cycling. I wear knee hi, open toe. Medi ven or futura are my favorite. I also lost 60 pounds last year, finally getting rid of my baby weight. My husband is ecstatic and so is my family doctor. I have very few spider veins because of wearing my sockies religiously.
