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 graded compression zones that provide support and relief from foot and leg pain, as well as accelerate recovery after intense training. Like other socks from OS1st, the FS4+ provides particular support for the plantar fascia (the tendon under the foot), reducing pain from conditions such as heel spurs.

The anatomical design provides optimal fit and support during training, while the compression promotes good blood circulation. This is crucial for maintaining muscle health and accelerating muscle recovery. 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 speed up recovery.

To find the correct size, you should measure the circumference of your ankle and calf. If you are 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, which makes them both durable and comfortable.

Use OS1st FS4+ for:

• Heel spurs (plantar fasciitis)
• Achilles tendonitis
• Shin splints
• Sore arches
• Faster recovery
