I’ve been using the Ergonx Slimline insoles for the past few weeks in my RM Williams Classic Craftsman (leather sole), and they’ve made a noticeable difference. I used to own a pair of Comfort Craftsman and really missed the cushioning and support they offered, but I much prefer the traditional look of the Classics. Unfortunately, my left foot arch pain was making the leather-soled Classics almost unbearable to wear.

There weren’t many slim orthotic options available, especially since the Classic Craftsman insole cannot be removed, until I came across the Ergonx Slimline. They add just enough cushioning and, more importantly, the extra arch support I needed, without pushing my toes up against the upper. My RM Williams are now far more comfortable and wearable for longer periods, without sacrificing the classic look I love. I highly recommend these inserts for dress shoes with non-removable insoles.

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.
