From the retailer:
We wanted to get in touch with you because we’ve identified a problem with the sandal shown above. You’ll find the item number (193426) on the heel strap.
Unfortunately, it’s come to light that there’s a potential problem with the star rivets, which could become detached, presenting a choking hazard to young children.
As the sandals don’t meet our strict technical specifications, we’ve taken the decision of recalling them, and we’re requesting that you return them to us for a full refund.
Please call us on 0333 777 8185 to arrange a collection, or return it to your local store (for a full refund), if this would suit you better. If you’ve given this item as a gift, please ask the recipient to get in touch with Next.
We’re very sorry for any disappointment and inconvenience this may cause, but we hope you’ll understand that customer safety is our highest priority.
