Unlike cheap compression socks that lose effectiveness after a few washes, BaseCompress uses medical-grade materials engineered to last. Our premium 85% Nylon / 15% Spandex blend maintains over 95% compression through 100+ washes. Medical-grade silicone bands stay up for 12+ hours, and reinforced heel/toe zones prevent holes. Every batch is independently lab-tested for compression accuracy and durability. Professional quality that lasts 4-6 months of daily use.
