Product Overview

The Yellowstone Mid Boot from the Base Record collection is a sophisticated fusion of athletic performance and rigorous industrial safety. Designed as a mid-height ankle shoe, it offers a level of comfort rarely found in traditional safety footwear, primarily due to its innovative anti-fatigue technology. This boot isn't just about protection; it is about ensuring that those who spend their entire day on their feet return home with less physical strain. Constructed using recycled fabrics and eco-conscious linings, it reflects a modern approach to workwear that prioritises both the user's wellbeing and environmental responsibility.

Key Features

  • SlimCap Toe-Cap: A metal-free, lightweight toe-cap that is significantly thinner than standard versions, providing more room for your toes while maintaining 200-joule impact resistance.
  • SmellStop WeareEco Lining: An antibacterial treatment integrated into the lining that prevents the growth of bacteria responsible for unpleasant odours, keeping the interior fresh throughout long shifts.
  • Fresh’n Flex Midsole: A high-performance, puncture-resistant fabric insole that offers complete protection across the sole of the foot while remaining flexible enough to allow for natural movement.
  • Dry’n Air WeAreEco Footbed: This system promotes air circulation within the boot, ensuring moisture is wicked away and feet remain dry even in high-intensity environments.
  • S3S ESD FO SR Standards: Comprehensive protection including slip resistance on ceramic and glycerin, fuel oil resistance, and electronic discharge protection for sensitive environments.

Design & Performance

The core of the Yellowstone Mid Boot’s performance lies in the AirTech + Tpu-Skin outsole technology. This design allows for a substantial Reduction in the thickness of the hard outer sole, replacing it with a soft, cushioning layer that absorbs energy more effectively. The result is a boot that feels remarkably cushioned underfoot, mimicking the comfort of a high-end trainer while providing the structural integrity of a heavy-duty work boot. The upper is crafted from a durable recycled fabric that offers excellent breathability without sacrificing the robustness required for daily site work. Despite its sturdy appearance, the boot is designed to be as light as possible to prevent muscle fatigue during extended wear.

Why No Customisation?

While we are specialists in branding, we do not offer customisation on the Yellowstone Mid Boot. Safety footwear is a precision-engineered piece of Personal Protective Equipment (PPE). Any secondary processing, such as embroidery or heat-seal printing, could potentially compromise the structural integrity of the recycled fabrics or interfere with the ESD (Electrostatic Discharge) properties. To ensure your footwear remains fully compliant with EN ISO 20345:2022 standards and provides the intended protection, we provide these boots in their original, unadulterated form.

Use Cases

These boots are specifically engineered for professionals working in ESD-protected areas, such as electronics manufacturing or high-tech laboratories, where controlling static discharge is critical. They are equally well-suited for warehouse operations, logistics, and light construction where slip resistance and all-day comfort are paramount. Given the metal-free construction, they are also an excellent choice for individuals working in environments with security scanners, such as airports or high-security distribution centres.

Why MyWorkwear

Since 1976, MyWorkwear has been at the forefront of the UK workwear industry. From our base in Telford, we have spent decades sourcing products that meet the highest standards of safety and durability. We don't just sell boots; we provide expert-vetted gear that we know will withstand the rigours of the British workplace. Our longevity is a testament to our commitment to quality and our understanding of what tradespeople actually need from their equipment.

Practical Advice

To get the most out of your Yellowstone boots, we recommend pairing them with high-quality technical work socks. This will enhance the moisture-wicking properties of the Dry’n Air footbed. If you find yourself between sizes, the dual-width design (available for both men and women) ensures a more tailored fit. Remember that even the best anti-fatigue boots benefit from being rotated; if possible, allow your boots 24 hours to air out between uses to maximise the lifespan of the SmellStop lining.

Caring for your product

Maintaining your safety footwear is essential for preserving its protective characteristics and extending its working life. Regularly removing dirt and debris from the outsole will ensure the slip-resistance remains effective; a clogged tread pattern cannot grip the floor as intended.

If the boots become wet, they should be allowed to dry naturally in a well-ventilated area. You must avoid placing them directly on or near a heat source, such as a radiator, as rapid drying can cause the technical fabrics and adhesives to become brittle, leading to premature cracking or sole separation.

For the recycled fabric upper, a gentle brush or a damp cloth is usually sufficient for cleaning. Avoid using harsh chemical cleaners or solvents, as these can degrade the ESD properties and the Tpu-Skin outer layer, potentially rendering the boots unsafe for their intended environment.
