adidasUnisex Adult Alphabounce 2.0 Slide

i usually wear another known brand adjustable slide sport sandals with soft foam foot bed...they really make my back hurt , would these be better?

How many inches long is men's 10/women's 11 black color adidas alfabounce slide 2 ? is it amazon b098rdwvld?

Do these Adidas sliders have EVA with formamide?

What is the difference between this and the first ortholites?
