VR Clara 140 Knee Highs are the very best combination of Italian hosiery...
I've bought these to help prevent blood pooling (gravity isn't my friend). The impact of them on my ability to walk for long distances or stand for extended periods has been tremendous. I rarely have any of the troubling symptoms I suffered from before.
The stockings themselves are of very good quality, and maintain their strength, and although expensive, they are worth it (I have bought cheaper stockings and have twice gone through the heels in the same period). An unexpected benefit is that they are also warm in colder weather!
Service from the company is first class, with proper measurement and sizing, and expert advice easily available.
Highly recommended!
