Zizler [ 34 ] proved that any separable Banach space has an equivalent norm which is uniformly convex in every direction. It is also known that uniformly convex Banach spaces are super-reflexive [ 11 ] which shows that the class of uniformly convex is a lot smaller that the class of uniformly convex in every direction. Let C be a weakly compact nonempty convex subset of X. Assume X is uniformly convex in every direction. Let C be a nonempty weakly compact convex subset of X not reduced to one point.
