Engineered for road riders, the Supertech R Boots deliver race‑bred performance in Alpinestars motorcycle footwear refined by pro racing feedback. CE EN13634:2017 certified, they use a synthetic microfiber chassis with accordion flex zones, a breathable 3D‑mesh inner bootie, injection‑molded shin plate, TPU shifter panel, and replaceable TPU/aluminum toe and heel sliders, while a side zip, hook‑and‑loop lock, micro‑ratchet, and grippy rubber sole optimize fit, peg feel, and control.
