@thr@® insoles
Our @thr@® and @thr@®plus insoles are the most rigid, stable and highly-performing insoles on the market, offering a sturdy, secure and long-lasting base for your footwear.
In addition to the materials, we came up with a special manufacturing process that makes it possible to bond each layer together so as to create a cohesive single unit. The result is a rigid, stable product that won’t warp over time.
Hi-tech laboratory tests and simple everyday use have shown that it is easier to break a heel when trying to pry it from the shoe than to actually detach it or warp the @thr@ insole.
Ten years after the launch of @thr@®, thanks to the ongoing work of the R&D department in collaboration with Kiefer Von Zoe®, we have further improved the high-quality insole that we are known for, creating the @thr@®plus. By replacing both layers of KPB with NPU Green, we have improved the insole’s performance by 12.5% longitudinally and 23% crosswise (the more important of the two as it gives the shoe greater stability).
The chart below contains more details about the tests that were conducted, under identical conditions, on @thr@ e @thr@®plus:
These insoles are made in ways that are respectful of the environment and healthy for those who work with them and who wear them. In fact, @thr@® and @thr@®plus are made with Kiefer von Zoe® materials, composed of cellulose that is sourced exclusively from responsibly managed forests, without the use of dyes and harmful chemicals.
