Our vein specialists recommend compression of at least 20 mmHg for the best possible results. We also recommend choosing compression socks that are fitted by height, and not by standard S/M/L sizing. If possible, always opt for over-the-knee or thigh-high compression stockings, as these will provide maximum coverage (including additional UV protection in warmer months) and support both your calf and thigh with graduated compression. Shorter styles are available, but do not compress the entire leg and may be less effective at relieving your symptoms.
