When the Mizuno brothers started their sports business almost 120 years ago, they had one goal: to create something great. Today, Mizuno is known for its quality sports equipment and sportwear made for everyone, from weekend athletes to Olympians, in a range of sports from running to football to golf.
Mizuno sports shoes combine high functionality with eye-catching designs, attracting both top athletes and fashionistas. Designers take up to a year to design each shoe ahead of semi-annual exhibitions, with multiple color variations created for markets around the world. To keep up with growing global demand for designs, Mizuno started migrating from physical samples to 3D virtual samples.
With the addition of Adobe Substance 3D Collection to the 3D design workflow, Mizuno is creating realistic 3D designs in less time. In addition to eliminating the time and cost of sample creation, Mizuno also uses 3D models to support digital commerce and marketing.
Photoreal images in an hour
Sports shoes offer unique design challenges, combining both fashion and product design choices. The soles are typically made of rubber with intricate patterns added for grip, support, and aesthetics. The uppers are softer, often utilizing layers of mesh, leather, reflective fabrics, and other unusual materials. When preparing to create 3D renders of shoes, getting the right combination of colors and textures is critical.
“Adobe Substance 3D Painter makes it easy to apply colors, textures, and even small wrinkles or scratches that make the shoes look more realistic,” says Mr. Takashi Nakamura, Technical Designer, Design Section of Mizuno’s Global Footwear Product Division. “Adding details such as bumps and wear as materials, rather than baking them into the 3D models, allows us to use simpler models with fewer polygons. These low-poly 3D models are more versatile as we can more easily reuse them on other projects, such as websites, catalogs, and marketing.”
Mizuno converted its fabric swatches into 3D materials using Substance 3D Sampler. Designers can take these real-life scans and apply them in different ways to bring ideas to life, such as layering multiple materials, changing colors, and applying materials to specific areas of the render.
The node-based material creation workflow in Substance 3D Designer is particularly helpful when creating more advanced, custom materials for shoes. Designers use node-based graphs to generate repeating patterns, such as fabric mesh or lines of tread on the soles of shoes. If they want to change the pattern, such as widening spaces, they can simply adjust the numbers to generate a new pattern, rather than trying to paint again from scratch.
“Even though we’re working in 3D, the workflow feels very similar to something like Photoshop,” says Ms. Ikuko Okada, Footwear Designer, Design Section of Mizuno’s Global Footwear Product Division. “It took me less than a month to learn how to use Substance 3D apps. Now we can apply designs to a shoe much faster compared to 2D.”
Fast and sustainable virtual samples
The ability to create photoreal virtual samples changes how Mizuno approaches the entire design process. Shoe designers no longer work with 2D sketches, exploring their designs directly in 3D.
“The traditional design process bounces between 2D and 3D,” explains Ms. Ayuri Tsunoda, Footwear Designer, Design Section of Mizuno’s Global Footwear Product Division. “We think of the shoe in 3D, but then we would sketch it in 2D and wait for a 3D sample. There were frequent miscommunications where the sample wasn’t quite what we were imagining. We no longer have those issues with 3D virtual samples because everyone can see exactly what the designer’s vision is.”
The process of making physical prototypes often took several weeks and required a lot of material, labor, and shipping costs. Switching to virtual samples eliminates waste, helping Mizuno reach its sustainability goal of becoming carbon neutral by 2050.
