Inline Skates: the name describes it all! Also known as roller blades, these inlines will have their wheels in a single line, unlike quad roller skates which have two wheels in the front and two wheels in the back (attached to trucks with axles). Brakes often are found on the back of an inline skate (if at all), while quads have their brake, also known as a toe stop, in the front. Are you looking for a pair of inlines? Find these here!
