Fs4+ Compression Socks

Fs4+ Compression Socks are designed as an all-in-one running and recovery sock that effectively counteracts swollen ankles, heel spurs (plantar fasciitis), shin splints, and Achilles tendonitis. These functional socks combine five graduated compression zones that provide support and relief from foot and leg pain, as well as accelerate recovery after intense training. Like other OS1st socks, the FS4+ provides particular support for the plantar fascia (the tendon under the foot), which reduces pain from conditions such as heel spurs.

The anatomical design provides an optimal fit and support during exercise, while the compression promotes good blood circulation. This is crucial for maintaining muscle health and accelerating muscle recovery. The FS4+ also helps relieve pain in heels, arches, and sore leg muscles. They can be used both during and after training to provide extra support and accelerate recovery.

To find the right size, you should measure the circumference of your ankle and calf. If you fall between two sizes, it is recommended to choose the larger one. The socks are sold in pairs and are made of 20% Lycra Spandex and 80% Micro-Nylon, making them both durable and comfortable.

Use OS1st FS4+ for:

• Heel spurs (plantar fasciitis)
• Achilles tendonitis
• Shin splints
