Shoelace Fixation Guide

This guide describes how to mount the dorsal interface onto the shoe and secure it using auxiliary shoelaces for PrintExo.

1. Overview

The shoelace fixation method provides a non-invasive, shoe-agnostic interface that allows PrintExo to be mounted on standard lace-up footwear without permanent modification.

This guide covers: - mounting the dorsal interface onto the shoe, - routing and tensioning shoelaces for secure fixation.
