Does Blue Lagoon Premium Admission provide any sort of footwear

Hello,

My partner and I are visiting Iceland soon, we are working out what to pack and want to pack light. Right now our packing list includes a pair of slides for both of us, however, we only really feel like they would be used at our day at the blue lagoon and are hoping we can leave them behind. I googled footwear at the blue lagoon and the AI overview (that I don't trust), says, premium admission to the lagoon comes with complimentary footwear. I wasn't able to find that on the blue lagoon website so I am wondering if this can be verified by anyone who has been recently. Thank you!
