Fit Information (Based on 133 reviews )

What Customers Say
Customers say these sandals are super comfortable for casual wear and water activities. Many reviews mention sizing runs large, with most suggesting sizing down half to full size. While most praise the lightweight feel and versatility, some note issues with strap comfort and durability. Common feedback includes the sandals' good fit for beach and pool use. Frequent comments address the easy slip-on style and cushiony footbed, though a few mention concerns about toe catching and strap rubbing.
