Ventilation is the key to controlling how hot things get. Living in a hot, humid climate things can get sticky. The Alpinestars SMX-R series boot is perforated to get as much airflow as possible without sacrificing any of the protective features. Just like the SMX-R boot, the PU heel counter and curved calf protection are present along with the specially designed sole and toe shifter to increase feel. Go riding in this high performance street/race boot knowing that you feet are not going to be sweaty and roasted.
