The Sinergy Grip are white women's safety clogs made by U-Power. Comfortable and lightweight , they are part of the Lei&Lei and White68 & Black lines.
Main Features and Materials
- Design and Comfort: These are low-cut sandals with a strap. The anatomical fit/shape is Natural Confort 9 Mondopoint , designed for an optimal adaptation to the foot. The Sinergy Grip are nickel-free. Their weight for a size 42 is 0.827 kg.
- Upper: Made of Lucky Microfibre , a material that contributes to the lightness and resistance of the shoe.
- Lining: Uses Wing Tex air tunnel technology, designed to be breathable. Measurements show excellent water vapor permeability ( 24.7 mg/(cm² h) against a requirement of ≥ 2) and a high permeability coefficient ( 197.9 mg/cm² against a requirement of ≥ 20). The lining also features high abrasion resistance, both dry ( 25,600 cycles ) and wet ( 12,800 cycles ).
- Toe Cap: Equipped with AirToe Composite , a non-metallic toe cap that offers protection. This toe cap guarantees a clearance height after impact of 20.0 mm and after compression of 20.5 mm , exceeding the minimum requirement of 14 mm.
- Anti-puncture: The Sinergy Grips do not have an anti-puncture system.
- Insole: It is a White Ergo Dry , anatomical, covered in breathable, antifungal, non-slip, and anti-fatigue fabric. It has been proven not to suffer damage after 400 abrasion cycles.
- Midsole: In soft expanded PU .
- Outsole: Made of compact U-GRIP 68 PU , which is abrasion-resistant, oil-resistant, non-slip, and anti-static. It has an abrasion resistance with volume loss of 34 mm³ (limit ≤ 150), a flexural strength of 1.4 mm (limit ≤ 4), and a sole/midsole detachment strength of 3.4 N/mm (limit ≥ 3). The volume change for hydrocarbon resistance is 3.5% (limit ≤ 12%).
- Washability: They are easily washable, a feature of the White68 & Black line, to protect against invisible dangers such as bacteria, waste, organic and chemical residues.
Protection Class and Regulations
The Sinergy Grip complies with the European standard EN ISO 20345:2022 and are classified as Type "A" footwear. Their protection class is SB EA FO SR . The sole is specifically indicated as SB EA FO SRC .
Here's what these classifications mean in detail:
- SB (Safety Basic): Indicates that the footwear is equipped with a safety toecap resistant to an impact of 200 Joules and a compression of 15 kN. The values measured for Sinergy Grip exceed these requirements with free heights of 20.0 mm after impact and 20.5 mm after compression (minimum requirement ≥ 14 mm).
- E (Energy absorption in the heel region): The heel of the shoe has the ability to absorb energy [from previous conversation]. The Sinergy Grip absorbs 32 J , exceeding the 20 J required.
- A (Antistatic properties): The sole is antistatic, with an electrical resistance of less than 10^9 Ω.
- FO (Resistance to fuel oil of outsole): The outsole is resistant to hydrocarbons [from previous conversation], with a volume variation of 3.5% compared to the 12% limit.
- SR (Slip Resistance): The sole demonstrates high slip resistance on glycerin-coated ceramic tiles. The measured values are 0.39 (heel inclination 7°) and 0.33 (toe inclination 7°), exceeding the regulatory requirements (≥ 0.19 and ≥ 0.22 respectively). Another source indicates 0.40 for the heel.
- SRC (Slip Resistance on ceramic tile with water and detergent + steel with glycerin): This is the highest level of slip resistance [from previous discussion]. The shoes were also tested on ceramic tile with water and NaLS (sodium lauryl sulfate). The measured values for NaLS are 0.46 (heel inclination 7°) and 0.41 (toe inclination 7°), significantly exceeding the regulatory requirements (≥ 0.31 and ≥ 0.36 respectively). Other values for NaLS are 0.45 (heel) and 0.42 (toe).
Areas of Use
These shoes are recommended for environments where work is carried out in hot weather and in the presence of chemicals . The White68 & Black line, to which they belong, is specifically designed for environments where protection from invisible dangers such as bacteria, waste, and organic and chemical residues is essential. They are ideal for professionals who desire comfort, style, and elegance even at work, as suggested by the Lei&Lei line.
Think of Sinergy Grip shoes as a high-quality surgical gown for your feet: they are designed to be impeccably clean and provide meticulous protection in environments where hygiene and safety against invisible threats, such as bacteria and chemicals, are paramount.
