Puma Sustainable Safety Vivid Green Heart Trainer
Description
The Puma Vivid Green Heart Trainer is where smart design meets sustainability. Part of Puma’s eco-friendly Green Heart range, this low-profile safety trainer is made using recycled materials without compromising on protection or comfort.
The upper is made from Safety Knit® Green – a flexible, breathable fabric that fits like a sock while keeping your feet cool throughout the day. Inside, the Evercushion Green insole adds lightweight cushioning and is also made from recycled content.
For protection, the trainer features a fibreglass toe cap and FAP® Green anti-penetration midsole, both completely metal-free. The rubber outsole is slip-resistant (SRC-rated), heat-resistant up to 300°C, and built to keep you steady in fast-paced or high-risk work environments. ESD and anti-static features also make this trainer ideal for sensitive areas like electronics or assembly.
