If you are really concerned about getting a bootie with the best traction, it is recommended to look for a bootie that has rubber bottom grips which cover the entire bottom sole for the maximum amount of traction. The Conda Baby Fleece Slippers are a great example of this type of style. However, the other types of rubber grips are just as effective and have their own advantages. Booties that have rubber grips in a circular pattern on both the heel and ball of the footwork like suction cups and mold themselves to the shape of your baby’s foot. Because these rubber grippers are only concentrated in the areas where the foot makes the most contact with the floor, they are highly effective at preventing trips and falls.
