I suspect your shoes are too narrow as well. Remember, your feet do swell a bit as you ride.
I get this numbness on toes and ball of foot too if I'm wearing too narrow roller skates or also if my biking PowerGrip foot strap is a bit too tightly set.
When I wear thinner socks and better fitting skates and/or if I loosen the PowerGrip strap a bit, the problem is gone.
