When temperatures rise, we enjoy long days, travel, and outdoor activities—until sweaty feet spoil the fun. Especially in summer, the interplay of shoe choice, material, and airflow determines how comfortable your feet feel. Lightweight, breathable fabrics can wick moisture away from the foot more quickly, boosting comfort. If you also look for a soft lining and choose styles that feel great even barefoot, you’ll notice every step feels more relaxed. In short: With the right setup, your feet stay fresh even on hot days—and your everyday life gets a lot more comfortable.

 

Why do feet sweat more in summer? Simple: Our body regulates heat through sweat—and your feet have an especially high number of sweat glands. High outside temperatures, longer walks, and little airflow in the shoe act like a turbo. Add dense, synthetic materials or fits that are too tight, and moisture quickly builds up. If it isn’t effectively wicked outward, a warm, humid microclimate develops—which not only feels uncomfortable, but can also affect comfort and freshness. The good news: With smart materials and routines, much of this can be avoided.

 

Five easy levers help right away: First, choose breathable materials that allow good air circulation. Second: Rotate your shoes regularly so moisture can evaporate. Third: Go barefoot when the lining is designed for it—it often feels especially good in summer. Fourth: Don’t forget care, like a short, cooling foot bath in the evening. Fifth: Make sure the width fits so your foot has room to breathe. Merino wool in particular makes the difference: it reliably regulates temperature and moisture, ensuring a naturally balanced foot climate—all day long.

 

Merino Slides

Looking for maximum airiness on hot days? Merino Slides blend the open, summery feel of a slide with distinctly refined comfort. A softly padded Merino-cork sole, cushioned cork footbed, and an ergonomic midsole pamper every step—customized with infinitely adjustable straps made from soft openwork knit. A robust, non-slip EVA sole gives you confident grip in everyday life, while glossy metal buckles and an upper made from recycled material perfect the urban chic. Office, vacation, or city: these slides deliver light, airy comfort with style—day after day.

Wool Sneaker

Prefer closed shoes but want summery lightness? The Wool Sneaker relies on extra-thin Merino knit and a super-light EVA sole—so every step feels featherlight. The soft Merino insole and removable footbed provide pleasant stability and make the sneaker a joy to wear even barefoot. Merino wool regulates temperature and moisture, is breathable, and naturally odor-resistant—ideal for long, warm days. Extra smart: the sneaker is washable at 86 °F (30 °C) and air-dries. For narrow to normal feet, the comfortable width F offers a pleasantly precise fit.
