  Magnetic skyrmions are envisioned as carriers of information in racetrack
storage devices. Unfavorably, the skyrmion Hall effect hinders the fast
propagation of skyrmions along an applied electric current and limits the
device's maximum operation speed. In this Rapid Communication, we show that the
maximum skyrmion velocity increases by a factor of 10 when the skyrmion Hall
effect is suppressed, since the straight-line motion of the skyrmion allows for
the application of larger driving currents. We consider a ferromagnet on a
heavy metal layer, which converts the applied charge current into a spin
current by the spin Hall effect. The spin current drives the skyrmions in the
ferromagnet via spin-orbit torque. We show by analytical considerations and
simulations that the deflection angle decreases, when the spin current is
polarized partially along the applied current direction and derive the
condition for complete suppression of the skyrmion Hall effect.
