AI Technical Summary
Existing insoles lack a clear definition of an effective minimum amount of sorptive materials, leading to inconsistent moisture and odor absorption performance.
An insole containing at least 10 grams of a sorptive material, with at least 30% by weight being zeolite, optionally including activated carbon, silver, and/or zinc compounds, to ensure reproducible and sustainable moisture and odor absorption.
The solution provides a technically verifiable and effective insole with enhanced moisture and odor absorption capabilities.
Abstract
Description
Technical field
[0001] The invention relates to an insole for shoes, in particular for everyday, work, sports or leisure shoes, for absorbing moisture and reducing odor formation during wear. State of the art
[0002] Insoles containing zeolite, activated carbon or antibacterial additives are known from the prior art, but without a clear definition of an effective minimum amount, which often limits the sorptive effect. Object of the invention
[0003] The object of the invention is to provide an insole that enables reproducible and sustainable moisture and odor absorption through a defined minimum mass of sorptive materials and a defined minimum mass of zeolite. Solution to the task
[0004] The problem is solved by an insole containing at least 10 grams of a sorptive material, wherein the sorptive material comprises at least 30 percent by weight of zeolite. Preferred embodiments - In a preferred embodiment, the mass of the sorptive material is at least 15 grams. - In another preferred embodiment, the zeolite alone has a mass of at least 10 grams. - In another preferred embodiment, the zeolite content is at least 25 percent by weight. - The sorptive material may also contain activated carbon. - The sorptive material may also contain silver and / or zinc or their compounds. - The introduction of the sorptive material is independent of the design of the insole. Advantages of the invention - clear differentiation from standard insoles on the market - technically verifiable effectiveness - high flexibility in the constructive implementation
Claims
