The Right Shoe Project
Shoes are made in many factories around the world and even models within the same brand can be quite different. To assist our customers in choosing the right size, we measure every shoe we receive. All this information is compiled so you can simply enter the length of your foot in centimetres, choose your preferred fit, and our calculator will recommend a size for you! Then, as you browse the website across various brands and models of shoes, we will provide a recommendation of your sizing in each model.
Still not sure? If you're in Brisbane, feel free to come in to our store in Milton for a fitting. Otherwise, you can contact our team for assistance and advice. If you would like to contribute to helping other customers please contact us with your shoe size, foot length and how well your shoes fit.

The Gruezi Biopod -4C DownWool Subzero 185 is a premium three-season sleeping bag, designed for trekking, biking, backpacking, and camping. Its innovative DownWool filling—a blend of 70% high-quality down and 30% moisture-regulating wool—ensures optimal insulation and climate control, keeping users comfortable even in lower temperature ratings down to -4°C (25°F). The mummy shape enhances warmth while maintaining a lightweight, compressible design. The adjustable hood, collar, and head pillow pocket provide extra comfort, while the two-way, auto-lock, anti-snag zipper with reinforced strap and cover allow for smooth operation and prevent heat loss. Foot ventilation and a spacious footbox ensure airflow when needed, and Feater loops allow compatibility with the Feater heating system. Built with durable, water-repellent, and PFC-free materials, this OEKO-TEX and Responsible Down Standard (RDS)-certified sleeping bag is also machine washable for easy maintenance.
