Rubber mat.

My workshop floor is 6" of concrete and I use re-cycled 1/2" thick rubber conveyor belting which does for the mill and workbench, I use thick rubber mats at the lathes.

+2 , still going well after 4 years; have spread & puckered up in a couple of places so will trim.. eventually.

Make that +3, these foam linked squares have proved to be a great covering over my concrete floor for the past few years and have saved several carefully machined parts from damage when they've slipped through oily fingers! The only downside that I've noticed is that if I drop a small item, my less than perfect hearing doesn't detect where it fell and the said item will tend to bounce away into some hidden corner.

I used to have those linked square mats but they don't like weld splatter! I was given some heavy ribbed rubber matting from a horse box, its about 15mm thick and tough as old boots, the ribbing helps with insulation of course.

Machine Mart has rubber matting on the roll, in several thicknesses and surface patterns.

Rubber?

I introduced some homemade wooden duckboards into my workshop last year - and have not looked back. They provide a lovely mechanical spring that synthetic materials dont. I just kick them around the floor to where they're needed, and you can make them to the 'right' size.

+1 for Martins chipboard flooring.

I used the 8 ft x 2 ft waterproof, sealed surface, underflooring sheets (green then) on top of my concrete floor. The ordinary stuff had a softer, fluffy (ish) surface. Nearly 20 years in its proved very durable. Strong enough to take industrial sized machines and stands up to limited welding splatter just fine. The offcuts made nice shelves.

My floor is 8" of re-enforced concrete over 6" polystyrene sheet on a type 1 fill base. Never seems to get really cold.

I bought some of that 3mm ribbed stuff to make a boot liner for my car (muddy dog proof). Beware it absolutely stinks for a few days, but wears off eventually

Concrete floor covered with sponge rubber matting with 12 mm painted chip board on top has a slight spring when walking on it. quick clean up with a brush any spills mop up off the painted surface.

My last two garage workshops had concrete floors and were terrible in winter. Any finished parts accidentally dropped were often damaged. I tried various mats but they ended up being swarf traps making clean up extremely tiresome. My current workshop cabin is on a concrete base but it has a 50mm frame infilled with insulation. This was then topped with floor boards and then 8’ x 4’ sheets of 9mm ply. Final finish was two coats of floor paint. It’s really good underfoot and very easy to sweep clean.
