These crib trainers are new to the Adidas website. They are available in sizes 1-8 which is good as my daughter, Symphony has broad feet so getting her size in crib trainers is hard and her feet are not yet strong enough for normal trainers.
They're priced at £25 which is good.
I've always said the internet is the best place to get stuff.
I also saw these adikids crib trainers. These trainers are £20.00
