in a long and warm 1% slope line (therefore it expands): what shoes do you use? straight shoes or inclined shoes?

- in the case of inclined shoes: the dilation of the line is in the inclined direction with respect to the horizontal and therefore tends to lift the shoe. but line can lower under the weight and the bottom of shoe rest on beam.

- in the case of using classic straight shoes: the base of the shoe is aligned with the pipe so it is inclined with respect to the horizontal: with the axial expansion the shoes can be stuck and blocked on the underlying beam. the solution may be to insert a rod between the shoe beam.

what solution do you usually use?

in caesar the shoe is "point" but in reality it has a lenght that stop rotations. how do you model them and what real shoe do you use?
