Stonz booties are designed with a wide opening to slip on easily over bare feet, socks, slippers, shoes or Stonz Linerz. They have an outer sole made of rubber, a durable coated nylon outer and a warm fleece lining that is water & wind resistant to keep little feet warm and dry in all weathers. Two toggles at the calf and ankle allow you to customize the fit and ensure the booties stay firmly in place! Perfect for baby wearing in slings and baby carriers, as you can layer up with socks, Stonz Linerz, or lightweight shoes inside the booties for extra warmth. The Stonz are also ideal for cruisers and new walkers with the non-slip sole and lightweight, soft-soled design of the booties allowing your child to walk freely and take their first steps outside without any restrictions or hindrance to their feet.
