The washable white ones are very easy to use and highly recommended. These LURAD beach sandals can also be worn in town. I've borrowed the AVIREX tag as there isn't a LURAD tag. The size is marked as 285 (2.5) on the bottom, but the paper tag at the time of purchase said 30cm, and they fit my 30cm family member perfectly. The actual size is about 31.5cm as shown in the photos. I'm looking for something tough and reliable because my weight puts a lot of stress on the thong part, which makes it difficult to find. I bought several pairs, but the ones I'm currently wearing seem like they won't break, so I'm listing one before the EVA material deteriorates. They are very comfortable to wear. I will ship them via post, so the packaging will be simple. Thank you for your understanding. #OOFOS #TAW&TOE #AVIREX
