Today, I walked on Pneumatit concrete for the first time – a special experience that is difficult to describe adequately. The concrete feels soft and springy when walking on it, both with shoes and barefoot. This is a very peculiar sensory perception because Pneumatit concrete is as hard as regular concrete, which can easily be verified with a glass. When standing on Pneumatit concrete, there is a noticeable sensation of warmth in the feet and lower legs. However, this feeling is different from physical warmth. It feels more like energization.
