Alpinestars Sektor Vented Shoes Alpinestars Sektor Vented Shoes use durable lightweight microfiber to protect against abrasion without adding extra weight. Perforated microfiber panels flow air to keep your feet cool when the temperatures rise. Alpinestars' speed lacing system and ankle straps make slipping into the Sektor boots quick and easy without undermining security. External TPR material at the toe helps to reinforce against abrasion. Note: We have found that this boot runs smaller than most, we recommend sizing up one size. This is also a narrow boot and would not be the best fit for riders with wide feet.
