The pair I reach for before every run

The pair I reach for before every run. I've been a huge fan of the HiFi for a few months now and use them as often as I can, especially on long runs as they have proven to not cause any blisters, irritation or hot spots. The ventilation (sun roof) across the toes is excellent and I notice a difference compared to other running socks. The courierPOD™ technology is clearly what makes the product stand out and is the perfect amount of cushioning for a training/racing sock. Lastly, they've nailed the compression sweet spot. It's neither too tight or too loose. Cannot recommend these enough!
