  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 $\alpha={d \log
\rho \over d \log r}$ 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.
