We like Nitro's Select TLS Boot's quick-response and confident support. It has a removable tongue stiffener to fine-tune the boot's flex to match your riding style, while the advanced TLS 5 Twin lacing system ensures a comfy and secure fit every time. The TLS 5 lacing system makes it easy to individually adjust the tightness of the upper and lower halves of the boot, and when you're ready to get out of your boots, simply give the Bail Out tab a quick pull and the shell opens without a fuss.
