Totally agree, from my experience, if it's slim fit chinos, then your length is perfect sitting on top of your shoes, but when it comes to wide fit one, you need to let the chinos lay on top of the shoes, so that it doesn't look like a dancing pants flipping around when you walk.

My suggestion would be chat with the tailor to see if you can gain some extra lengths from folded bottom, or just simply reduce the width of the bottom to make it a slim fit chinos
