Too light? For me, yes. They are basically made of neoprene (I don't know what Reebok calls it) and the soles are more sure than Sk####ers Go Walks but not enough for me. Light as a feather with good support for the way the shoe is made. Would probably be great for packing for travel because they won't tip the scales and would pack a little flatter. I measure a 7 but my foot being a bit wider I usually wear a 7 1/2 and they fit perfectly (at times I wear an 8 in a high pump if that helps). Sadly I'm sending them back because I am traveling where the streets and sidewalks are made of cobblestones so you need a firmer bottom on a sneaker/shoe. But they sure are cute!  Hope this helps.
