Out of the box, the Tropicfeel Sunset feels light and flexible, requiring virtually no break-in period. The knit upper is soft and adapts well to the foot, making them comfortable for casual wear and suitable for going sockless in hot weather. The collapsible heel is a genuinely useful feature for quickly slipping them on or off at airports or beaches. During my Southeast Asia trip, this was great for quick changes from street to temple (where shoes off is a must) – especially in places like Chiang Mai where you might visit several temples in a day. Exploring the chaotic, vibrant Chatuchak Weekend Market in Bangkok was another test – they were breathable enough for the heat (even after 15,000+ steps through the sweltering maze of stalls) and easy to navigate the crowds in (once I'd upgraded the insoles!).\n\nHowever, the comfort story changes dramatically when it comes to support. \*\*The included insoles are notoriously thin and flimsy, offering minimal arch support.\*\* This is the most consistent complaint from users, and my testing confirms it – long walking days become uncomfortable without swapping in substantial aftermarket insoles. \*\*Consider high-quality insoles an essential additional purchase.\*\* I put in a pair of Superfeet and the difference was night and day; suddenly, they were a viable all-day shoe for exploring Bangkok's markets and even some light trails in national parks. Some users also report the ankle opening can feel tight, though this wasn't a major issue in my tests. The quick-dry magic of these shoes is undeniable though; after getting caught in a Bangkok downpour that flooded the streets, they were damp but wearable within an hour or two of air drying back at the guesthouse.
