Do you want to protect your sneakers but don't know which spray to choose? The market is full of options, from cheap supermarket sprays to premium sneaker care brands. In this article, you will read what to look out for so that you make a choice that truly protects your sneakers.
Water-based vs. solvent-based
This is the most important distinction. Solvent-based sprays contain chemicals that can damage, discolor, or dry out materials, especially suede and nubuck. Water-based formulas are safer for the material, safe for indoor use, and kinder to people, animals, and the environment. REINS crystalline protection is 100% water-based and free of PFAS and microplastics.
Material suitability
Not every spray works on every material. Always check if the spray is suitable for your sneakers:
- Fabric & canvas: most sprays work, but water-based formulas penetrate better.
- Leather & synthetic leather: avoid sprays with alcohol, as they dry out the leather.
- Suede & nubuck: extra sensitive; use only sprays explicitly approved for this.
- Mesh & flyknit: thin layers are crucial; coarse sprays clog the structure.
- Synthetic & rubber: often overlooked, but also worth protecting.
REINS crystalline protection is suitable for all the above materials. Not suitable for high-gloss patent leather shoes and greased shoes.
Duration of effectiveness
Cheap sprays often only last 2-4 weeks. Premium formulas last longer. REINS crystalline protection works for at least six months per treatment, which is 6 to 12 times longer than most standard sprays.
Application: spray vs. atomizer
Traditional aerosols produce a coarse, uneven mist. An ultrasonic atomizer, such as the REINS atomizer, creates an ultra-fine mist that reaches every fiber, even in seams and perforations. Result: more even protection, less product consumption, and no white spots.
PFAS and safety
Many classic water-repellent sprays contain PFAS (also known as forever chemicals), substances that are harmful to humans and the environment and are being increasingly strictly regulated in Europe. Always choose a PFAS-free formula. REINS is completely free of PFAS, microplastics, and harmful chemicals.
