Fantastic product! They fit into my rm William s boots perfectly. I need arch support without too much of the boot being filled up. I would highly recommend these to anyone.

So good I ordered more the day I put them in, they are exactly what I have been looking for. The fit is perfect, not felling around the edges and not pressure on top of the foot, just perfect conformity around the foot to support the areas that need it most. Well done.

My boots were fitting me quite well, but after the insole, it became a bit tight. that said...I think it's probably as expected with an insole. it did provide me with more support and made it easier for me to stand for longer period of time in my RM comfort craftsman.

Very happy with these products. I am using almost all of the ergonx range of innersoles in my shoes (some shoes can use the full innersole and some need the half or slimline innersole). They literally have one for every purpose and most importantly they work. My knee pain has completely gone.
