tannuki and 4T2 come together through shared values: a love for running, local culture, and creating pieces with intention.
in ultra running, every race begins with a goodbye - to friends, family, and the comfort of routine. once you step onto the course, you move thru highs and lows shaped by weather, terrain, your body, and your mind. this design captures that journey: the high from the start, the inevitable dip in the middle, and the climb again as you push toward the finish. it’s the rhythm of every ultra.
the word sayonara, the name of our ultra shoe, blends with the tannuki ,,u’’ logo to form sayounara, a small japanese-western twist that reflects both brands. a silhouette that balances performance and a relaxed fit.
quick-drying, lightweight, stretchy, and built to handle long days out there - whether you’re chasing a high or fighting through a low.
