    in my opinion the most direct approach to reduce them is smaller first layer height like 0,2 maybe 0,1 mm. But that needs a perfectly levelled bed.

    i am working with 0.1 first layer.( on cura)

    there is a way on cura that i can change the height between the layers ? ( all of them supposed to be the same )

    usually, the elephants foot only happens at the very first layer, but yours seems to be several layers high. I can't see it on the pictures. does it go narrow shortly after the first layer and then some layers later a bit wider again? This could be the fans turning on. Maybe set "fan full on at layer" to a higher value and reduce fan speed a bit? But I think you have to live with that effect to some extend. If it is your own model, maybe add a notch to the bottom to compensate for the foot?

    If you go to the Advanced tab, under Quality, you can set "Initial Layer Thickness" to whatever you want - i.e. just the first layer. On Basic tab, under Quality, you can set "Layer Height" to whatever you want - this will apply to the 2nd and all subsequent layers. There are a couple of Cura add-ons that let you adjust certain settings at chosen layers but I am not sure if you can adjust the layer height; think not but I could be wrong.

    Picking up on @avogra 's point if it is your model then reduce the dimensions of the 1st layer by .1mm (say, you may have to play around to get the exact dim.)
