The insole provides pleasant and even heat for up to 9 hours, keeping your feet warm and comfortable all day long. The heat-activated reaction of the insole starts simply by opening the package, making it quick and effortless to use.  <\/p>\n<p>The heat in the insole is generated from natural ingredients that react with air. The ingredient list includes iron powder, water, activated carbon, vermiculite, and sodium chloride. The combination of these ingredients creates a thermal reaction that maintains comfortable heat for a long time. Activated carbon and vermiculite help regulate and keep the heat even, while iron powder and water trigger the chemical reaction to produce heat.   <\/p>\n<p>This heated insole is an excellent choice for outdoor activities in winter, and it brings comfort to situations where you move in cooler conditions for longer periods.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Disposable heated insole for use inside shoes.<\/p>\n","protected":false},"featured_media":7068,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[438,411,3605,3325],"product_tag":[4424,4391],"class_list":["post-13412","product","type-product","status-publish","has-post-thumbnail","product_cat-camping-equipment","product_cat-clothing","product_cat-textiles-en","product_cat-winter-trekking","product_tag-disposable","product_tag-thermal-insole","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Disposable Heat Insoles 2pcs S, 23cm \/ 36-38 - Retki Finland<\/title>\n<meta name=\"description\" content=\"Disposable heated insole for use inside shoes.
