The Juzo Dynamic Max is a high-quality, therapeutic-grade compression stocking designed for medical needs. It provides firm compression in the 20-30 mmHg range, which is typically prescribed for managing conditions like edema (swelling), lymphedema, varicose veins, and advanced venous disease. The 'Dynamic' part of the name refers to its design, which is meant to support an active lifestyle with a comfortable, secure fit. This style is knee-high (or 'short') and features a 3.5 cm silicone top band that helps keep the stocking in place without digging in or rolling down. The 'Max' indicates it offers a high degree of containment. The color is a neutral beige, making it discreet under clothing. It's unisex, so it can be worn by both men and women. The size 3.5 refers to the calf circumference measurement range it's designed for – it's crucial to measure yourself accurately according to Juzo's size chart to get the proper medical benefit. They are extremely durable and can be machine washed and dried. These are medical devices, so it's always best to consult with your doctor to ensure this is the right compression level and style for your specific condition.
