Birkenstock Boston EVA clog in Black.

Birkenstock Boston EVA clog in Black. Unlike the traditional leather or suede Boston clogs, this version is crafted from a single piece of lightweight EVA (ethylene vinyl acetate), making it completely water-friendly, flexible, and easy to wash. It maintains the brand's signature anatomically shaped footbed for arch support while offering a more casual, pool- or garden-ready alternative. Key Features Material: 100% EVA (upper, lining, and sole). Design: One-piece molded construction with an adjustable strap and tonal buckle. Functionality: Waterproof, ultra-lightweight, and shock-absorbent. Birkenstock size 39 (EU) generally fits a US women's 8–8.5 or a US men's 6–6.5.
