This is my review of Revolutionary New Massaging Liquid gel Insoles that actually work (UK 6 – 7).
The delivery and refund service were excellent but I disliked the way that the thin layer of liquid gel inside the insole slides about with every step – a bit like walking on a water bed. I'm more used to gel that is solid, but "gives" to pad one's feet.
Although I take size 7 shoes, my only choice was to purchase insoles size 6-7, which meant they fitted in my shoes easily, but left a small gap top and bottom. This was less of a problem than the gel in perpetual motion. I was also worried about the possibility of the gel leaking over my shoes as the insoles wore out.
The insoles seem more expensive than some "solid gel" alternatives which I have found more effective and comfortable, apart from the disadvantage of having to cut them to size.
