Who Are AllBirds?

AllBirds produce shoes for men, women, and children alongside a small range of activewear. AllBirds manufacture shoes without flashy logos and senseless details. Instead, the brand focuses on comfortable shoes made from natural materials designed to be practical. While many brands opt for cheaper synthetic fabrics; AllBirds has taken a stance against this, using merino wool alongside other elements (see materials category). Lastly, AllBirds is a certified B Corporation, meeting strict environmental guidelines.

What are AllBirds Trail Runners SWT

AllBirds Trail Runners are advertised and listed as an active shoe with features including a sturdy outsole grip for hiking trails and a snug sock-like collar, which blocks debris. The shoe also features a tear-resistant ripstop mudguard to protect your feet from tough terrain. The following description is how AllBirds describe this signature pair of shoes.

AllBirds created the shoes with rugged trails in mind; the shoe is designed to be durable, comfortable, and perform well across many terrains. The high performance of the shoe allows you to explore the unbeaten path thanks to a breathable one-piece upper featuring durable ripstop protection, rugged, all-condition traction, stabilising midsole support, and a sock-like collar that blocks debris. AllBirds SWT (Sugar, Wool, Tree) represent the combination of the cushion of SweetFoam, the comfort of wool, and the breathability of eucalyptus tree fibre. Their catchline and branding is on the natural rubber outsole, made from nature, for nature.

Primo Natura's Reflections.

Shoes are important to protect and support our feet on our everyday endeavours, from walking the streets or scrambling up a hill. Living in the UK and going on holiday to Scotland has taught me that if it is not raining now, it will later. Personally, I feel that many high street shoes are designed to look attractive; however do they preform well in rain, mud and rocky terrain?

After being recommended AllBirds by a friend I came across the Trail Runners which are advertised as a hiking, walking and trail running shoe. I chose a black sole as a white sole is impractical in mud. Since buying a pair of my own, my mum has bought a pair of new AllBirds and my dad got a bargain second hand pair on eBay.

I have always visited a shoe shop, tried on a pair before walking around the store to get a feel for the shoe. Unfortunately, this was not an option for me, as I bought my pair online. However, I felt reassured by the reviews saying that they are true to size and that AllBirds teamed up with Soles4Souls. Lightly worn AllBirds shoes can find a new life worldwide, helping communities in need thrive. AllBirds does recommend that if you have wide feet or prefer a roomier fit to accommodate toe splay, to go up a half size; for extra wide feet, go up a whole size.

Over the summer, I went on holiday to a remote Scottish island, allowing me to swap my usual walking around shops and paved roads for rugged terrain. If anyone is interested, I have posted images of my travels on my Pixelfed. On one of the most excellent days of the holiday, we explored a well-worn path for a few miles, which led to an old pier. As with any coastline area, there were plenty of stones (wet and dry) as well as seaweed. While I did my best to avoid the wet surfaces, the shoe supported my ankle and provided the necessary grip.

When wearing a walking or hiking shoes, you often require specialist socks, which are usually thicker than conventional ones. However, I wore regular socks beneath my jeans. During the trip, I was kneeling to get pictures, and with any walk, I accumulated mud. Despite accumulating Scottish mud, the shoes were easy to clean using an old bamboo toothbrush and water. AllBirds has produced a guide on how to wash your trainers should you wish to.

Overall, I recommend AllBirds as a brand for their environmental commitments, such as using high-quality merino wool, looking at ways to reduce their carbon footprint and transparency of where their goods are made. Transparency informs me that the shoes I bought are made in Vietnam and have a carbon footprint of 9.37 kg CO2e. The boots have a premium craftsmanship and minimal look, allowing me to feel confident when walking down the high street or scrambling in a forest.
