Union BOA Mountain Bike Shoe

TPU, or Thermoplastic Polyurethane, is a flexible and durable plastic used in the upper material of shoes. It provides a lightweight yet strong structure that can withstand rough conditions, making your shoes more resilient and comfortable for various activities, including outdoor sports.

The BOA® Fit System features a dial mechanism that allows you to easily tighten or loosen your shoe's fit. Unlike traditional laces, this system enables quick adjustments for a more secure and customized fit. The dual BOA Fit System includes two dials, allowing you to independently adjust different parts of the shoe for optimal comfort and support.

EVA, or Ethylene Vinyl Acetate, is a lightweight foam material known for its excellent shock-absorbing properties. It helps cushion your feet, reducing the impact when riding over rough terrain, which enhances comfort and performance during your biking adventures.

Ultratrac Rubber is a specialized rubber used in the outsole of shoes, designed to offer superior grip and durability. This is crucial for maintaining traction on slippery or uneven surfaces, especially in mountain biking, ensuring you stay stable and secure while navigating challenging trails.

2-bolt cleat compatibility refers to the attachment system used for bike cleats, featuring two holes for screws that connect to the shoe. This standard is common in mountain biking shoes, allowing you to easily pair them with various pedal systems, enhancing your biking experience and ensuring a secure connection.

The combination of TPU for durability, the BOA® Fit System for a customized fit, EVA for cushioning, Ultratrac Rubber for grip, and 2-bolt cleat compatibility all work together to improve your biking performance. These features ensure that your shoes are comfortable, secure, and capable of handling various terrains, allowing you to focus on enjoying your ride.
