Size Guide
Our shoes fit true to size according, simply choose your usual size when ordering.
If you're between two sizes, we recommend selecting the larger one for added comfort.
For more information, you can take a look at our size guide:
Are they slip-resistant?
The SOLYDIA MaxOne are SRC certified, the strictest slip-resistance standard in Europe.
This means they have been tested and approved on:
The SRC certification combines both tests, guaranteeing maximum grip on all surfaces — whether wet, greasy, or oily.
If your job requires slip-resistant footwear, the S3 standard fully meets those needs.
Are they waterproof?
The SOLYDIA MaxOne are water-resistant and certified WR (Water Resistant).
They provide effective protection against:
Perfect for all jobs exposed to moisture.
For which environments are they suitable?
The SOLYDIA are S3 certified, making them suitable for all demanding work environments:
✓ Hard floors (concrete, tiles, asphalt)
✓ Long periods of standing (6–12+ hours)
✓ Intensive walking (10,000+ steps/day)
✓ Handling heavy loads
✓ Wet or greasy surfaces (SRC certified)
✓ Risk of falling objects
✓ Risk of punctures
Whether you work indoors or outdoors, they meet all the requirements of S3 certification.
How does the rotary lacing system work?
The rotary lacing system works with a dial: turn it clockwise to tighten the shoe and counterclockwise to loosen it.
This technology allows for precise, millimeter-accurate adjustment in just 2 seconds, offering much greater speed and accuracy compared to traditional laces.
What’s the difference compared to my current safety shoes?
Our sneakers are 45% lighter than standard safety shoes while maintaining the same S3 protection.
The high-density Memory Foam insole eliminates foot pain, and the modern design looks just like real sneakers. You get the same level of safety with revolutionary comfort and style.
Do SOLYDIA really comply with the S3 standard?
Our sneakers are certified according to the European standard EN ISO 20345 S3, which guarantees a steel toe cap resistant to 200 Joules of impact, a Kevlar anti-puncture sole, water resistance, and anti-static properties.
All tests are validated by independent certification bodies.
Can I wear them all day without pain?
The high-density Memory Foam insole and lightweight construction are specially designed for long workdays.
Our sneakers have been tested during 12-hour consecutive shifts. If you experience any discomfort, we offer a full 30-day money-back guarantee.
Does the sneaker-style design hold up on construction sites?
Although designed with a sneaker look, our shoes use high-strength industrial materials: reinforced mesh, sealed stitching, and a professional slip-resistant sole.
They resist mud, dust, and splashes while remaining easy to clean.
How do I choose my size?
Our sizes run true to standard European sizing. If you are between two sizes, we recommend choosing the larger size for extra comfort.
