Any shoe that requires an instruction card in the box is going to pique our interest. The latest creation to come out of New Balance's innovative Tokyo Design Studios is the TDS Niobium Concept 1. The Niobium is three shoes in one, the mid-top can be unzipped to create a laceless slip-on, and from there, the inner bootie can be removed to create a slipper. In its complete form, the boot features a waterproof exterior, a suitable outer-sole for rugged terrain and of course, a New Balance specialty, maximum comfort. Available in either a muted black colourway in the MSNB1OL or a more vibrant yellow on the MSNB1YL.
