With help of a set of toy N-body models of dark halo formation we study the impact of small scale initial perturbations on the inner density profiles of haloes .
We find a significant flattening of the inner slope \alpha = { \mathrm { d } \log \rho \over \mathrm { d } \log r } to \alpha = -0.5 in some range of scales and amplitudes of the perturbations ( while in the case of absence of these perturbations the NFW profile with \alpha = -1 is reproduced ) .
This effect may be responsible for the formation of cuspless galactic haloes .
