See our Support Guide for information on support & compression levels, as well as the benefits of support. Super durable & packed full of a graduated compression, the Support 140 Tights from Cette are a must for tired legs. Made from a super strong 140 denier yarn, your tights actually have a much sheerer 30 denier appearance. The semi-sheers use an extra extra firm support (factor 21) to encourage blood circulation & keep your legs ache free. Offering the highest level of support you can get without a prescription, the tights are perfect if you spending long periods sitting or standing. Smooth & soft, the tights come with essential design features for a comfortable feel & chic look.
