What's the Difference Between TR and TPU Soles?
The material you choose for a shoe sole directly affects the weight, comfort, durability and price of the finished shoe. PROSPÓD offers soles made from two main materials: thermoplastic rubber (TR) and TPU. Below, we explain how they differ.
TR Soles — Lightness and Flexibility
Thermoplastic rubber (TR) is a material that combines the flexibility of rubber with the easy processing of thermoplastics. TR soles are lightweight, flex well — even at lower temperatures — and allow for vivid colors and precise tread patterns. It's a popular choice for everyday and sports footwear.
TPU Soles — Comfort and Durability
TPU is ideal where long-term wearing comfort matters. TPU soles cushion well, are lightweight, durable, and resist abrasion and many chemicals, making them a popular choice for work and protective footwear.
Which Material Should You Choose?
The choice depends on the footwear's purpose: TR is a great fit where lightness and appearance matter, while TPU wins where comfort, durability and resistance to harsh conditions are the priority. If you're not sure which material is best for your project, get in touch — we'll recommend a solution tailored to your specific shoe model.
