Great product, these go up to a uk adult size 7. Brilliant as my 12yr old already has size 5 feet. Not many heelys accommodate kids with adult sized feet. Get one size bigger than child's actual size as they come up a bit smaller, as, like all heelys, they are very well padded. (Size 6 fitted her size 5 foot perfectly)
These are of a two wheeled design, these are the safest statistics wise, and of course you can always remove a wheel if your child masters 2 wheels in no time and wants more challenge. This style does not come with a wheel removing tool, but it does inform you of this when you order. We already have this tool from owning previous Heelys, but I would imagine that it is quite easy to order and purchase one separately. Trendy black and red design and bought at an absolute bargain price. Prompt delivery and well packaged.
