We present α-attractor models for inflation based on \cal N=1 supergravity with flat Kähler manifolds. The function form of the associated Kähler potential in these models are logarithmic square in nature and has a visible shift symmetry in its composite canonical variables. The scalar potential V with respect to these field variables has an infinitely long dS valley of constant depth and width at large values of inflaton field ψ and attains a Minkowski minimum at small ψ. We illustrate this new framework with a couple of examples.
