Multiple outlets report on advice from a footwear expert about what people should avoid wearing during heatwaves. The articles frame the guidance as a practical “no-no” list for hot conditions, using recent beach appearances by public figures as examples. One piece notes that Angela Rayner is pictured at Brighton Beach wearing white Crocs on the Bank Holiday weekend, presenting them as part of a heat-appropriate footwear choice in the coverage. It also contrasts that look with other common options people might consider in high temperatures, including sandals such as Birkenstocks, which the articles reference in the context of summer footwear. The same coverage also mentions a separate fashion trend associated with another figure, describing “sock and sandal” as a divisive style. Overall, the reporting combines expert heatwear guidance with celebrity imagery, but it centers on the idea that some footwear materials and styles can worsen comfort in hot weather, while others may be better suited for heat conditions.
