When I had to put no weight on my foot at all I used crutches. There are a number of types of crutches:

If you go for crutches, Make sure you get the type with the "bracelet" (bottom of the picture) and make sure the "bracelet has a hinge -- that way you can let go of the one crutch while leaning on the other, and you have a free hand to open a door (home, car) prepare a cup of tee or coffee, etc while the free crutch is dangling on your arm above the elbow. Also note that some crutches are lighter than others. The armpit type of crutches, and the ones with a bracelet and no hinge give you less freedom.
Make sure you have a physiotherapist teach you how to use whichever device you get.
At a certain stage of my rehab, I used only one crutch.
I've never used a walker, but have seen it in use. Given a choice, - and having the upper body strength (it develops very quickly...) I would prefer crutches - but that's me .
Another major difference between crutches and a walker is that you need to agility to be able to bend down to the floor and pick the crutch up if you're sitting -- they may slip from wherever you've leaned them on - it is often better to place them on the floor. This never happens with a walker (as long as you haven't folded it).
Good luck!
