9 Sustainable Knit Shoes & Sneakers

Knit sneakers are the newest shoe trend we can definitely get behind. When choosing a pair of knit shoes, you want them to be breathable, comfortable and not to mention, stylish.

Here we discuss our favourite sustainable knitted shoe styles, and where to buy them.

Through 3-D knitting technology, some brands are able to reduce waste by up to 30% compared to conventional cut and sew techniques. In addition, brands are using eco-friendly and recycled materials, to create their stylish knit shoes.

Knit shoes have grown in popularity in the past few years. We’re not talking about your grandmother’s old fashion handmade knit boots – we’re taking new innovative knit sneakers and shoes – But what are knit shoes?

Well, knit shoes are a type of shoe that’s made with knitting technology. The shoes usually feature a tight-knit weave made of wool or a plastic-based fiber. As we’ve said, knit shoes have grown in popularity, and that’s partly thanks to knit shoes being lightweight, comfortable, and breathable.

As we’ve said, knit shoes have grown in popularity thanks to being lightweight, comfortable, and breathable. It’s even calculated that the global knitted footwear market is forecast to grow to US$3,195 million in 2025, an increase in over $1 million from 2017. Below we’ve included a few reasons that make knitted footwear so popular.

  • Breathable – Knit shoes have micro pockets of air that allow air to escape the shoes which makes them breathable. Breathability in shoes is essential to prevent your feet from getting sweaty and overheating. No one wants to stand all day with sweaty feet. It’s uncomfortable and can be bad for foot health.
  • Lightweight & Comfortable – Innovative technology in knitted shoes means they’re now some of the most lightweight shoes on the market, overtaking heavy shoes like leather and PU-based plastics. Lightweight shoes are great for all-day wear as they won’t cause leg aches like a heavy pair of boots sometimes can.

Now we know what knit shoes are and why they’re so popular, let’s jump in.
