Why did a sock company launch Performance Shirts?

Since 1999, Injinji has been a trusted name in designing high-performance toesocks for the running community. Now, we’re expanding our commitment to comfort, performance, and support with the introduction of the Performance Shirt Collection. We know that performance gear isn’t just about socksit’s about the complete package. Every runner needs durable, versatile layers that complement their active lifestyle, and these shirts do just that. Whether you’re running through city streets or conquering rugged trails, the new shirts are crafted to fit seamlessly into your routine, keeping you sweat- and irritation-free every step of the way.

What features make the performance shirts a must-try? 

For active individuals who want the perfect blend of lightweight performance, unrestricted range of motion, and durability, these shirts are an ideal choice. Here are the key features:  

  • Ultra-Soft Stretch Fabric: Made with exceptionally smooth fibers for next-to-skin comfort and unrestricted range of motion. Seriously, this might be the softest shirt you’ll ever wear.

  • Moisture-Wicking: Quick-drying fabric that wicks sweat and helps you to perform at your peak.

  • Anti-Chafe Neckline: Strategically placed seams protect the skin from running vest and backpack irritations.

  • Run & Rest Day Ready: Designed for both high performance and low output days.

  • Travel-Friendly: Packs down light (rolls into the size of a burrito) for daytrips and multiday journeys alike. Throw it into your gym bag, running vest, or into your 70L backpack-across-Europe pack.

  • Short Sleeve and Long Sleeve Styles: Optimized for multi-season adventures. The short sleeve top is perfect for warmer days and the long sleeve piece is a dynamic layer that’s light enough to wear solo on sunny days, but warm enough to layer on cooler days. 

  • Men’s and Women’s Fits: Performance Shirts come in Men’s and Women’s fits that are tailored for the unique needs of our bodies on-the-go. Women’s shirts feature a semi-fitted silhouette and Men’s shirts feature a relaxed fit.
