The multi-award winning Spin Ultra is the perfect choice for moderate to ultra distance runs, and has quickly become SCARPA's best-selling trail running model. Hitting the sweet spot between precision and sensitivity and cushioning and protection is not easy, but the Spin Ultra does just that with the dual-density EVA midsole paired with our Vibram Velox LB Max outsole. This combination underfoot, paired with the all-synthetic, lightweight yet supportive upper construction makes the Spin Ultra ideal for just about any trail running adventure, from shorter runs close to home to ultra distance training or races in the mountains, and everything in between. The Vibram outsole features 4mm deep lugs and Megagrip rubber, which offers confidence-inspiring traction in loose dirt and mud, as well as on rock. The mesh and welded PU upper and Sockfit construction is light and breathable but still provides foot-wrapping support and a secure fit. Attention to detail is evident in the less prominent but still functionally key features like the Hidden Lace Pocket and molded TPU toecap. All of these elements come together seamlessly in this go-to, quiver-of-one trail running shoe.
