Adults and youth with growing feet will love the V-Tech 500. The inline skates adjust from adult size 6 to 9 at the push of a button. Three buckles make the skates easy to put on and take off, and provide a solid level of comfort and support. The boot and liner have extra ventilation to keep feet cool on long sessions and are washable if you need to freshen them up. The ultra-lightweight design is great for beginner to intermediate skaters who want more freedom and movement in each stride. These skates are breezy and fast, featuring smooth-rolling 76mm urethane Speed Formula wheels that absorb vibrations in the road and have great grip for turning tight corners. They are loaded with high-end Gold-7 Race Rated chrome bearings which are built for speed. Use them indoors or outdoors, on rinks, roads, sidewalks or floors. These adjustable inline skates for teens, children, and adults fit true to adult shoe sizes 6-9. Roller Derby is America's Skate Company since 1936.
