Shorts for bigger thighs

[OakLeaf]

I have the Castelli Visio.1 shorts, and the grippers are loose while the rest of the shorts fit fine.

FWIW, the Vizio.2 don't have grippers. They have a separate panel around the hem of each leg that's cut on the bias so it doesn't stretch as much as the fabric on the upper thighs. The waistband is similar. They don't ride up at all, on me, although the waistband does tend to roll over on my nonexistent waist.
