A black backless Birkenstock Boston-style slide with an adjustable instep buckle and an ergonomic footbed, listed across EU 35–46. The sizing record is category-level and split: one review says Birkenstocks generally run large, while Chinese-language wearers disagree on sizing down. Confirm footbed length with the seller before ordering, since no buyer evidence covers this exact pair.

Fit notes
Category reports lean generous: one review says Birkenstocks generally run large and buyers size down, while Chinese-language wearers split — some size down, others warn that sizing up shifts arch support off the foot and causes arch discomfort. Confirm footbed length with the seller instead of assuming.
Buy if
You want a backless, buckle-adjustable Birkenstock slide and will confirm footbed length against the brand's chart first. The adjustable strap and ergonomic footbed are the features the listing actually describes.
Skip if
You need a stated upper material or water-resistance spec before ordering, or you want full-day wear from day one — new Birkenstocks carry a reported break-in period of short sessions at first.
