A shoe sole includes a cover layer, and a cushioning member disposed on
the cover layer, for softly contacting and engaging with feet of users.
The cushioning member may be made of gel, or fluidity materials, or soft
materials, or the like. The cover layer includes an opening to partially
receive the cushioning member. A basic layer may further be attached to
the cover layer, and may include an opening aligned with the opening of
the cover layer, to partially receive the cushioning member. The opening
of the cover layer includes an area smaller than that of the opening of
the basic layer, to anchor and position the cushioning member in the
openings of the cover layer and the basic layer.
