It would be comparable to a fence post or a spear being shoved into the ground with all the weight of a teenage boy. Whenever it is lifting a leg, another 33% of weight is added to each of the three others. Had Xerneas had bigger feet, the pressure on the ground from the foot wouldn't have been a problem, but with its current design there is a lot of force spread out over a very little area, resulting in a sky high pressure, causing each foot to sink a fair distance into soft ground. It would be like a grown man walking on stilts whose ends were knife blades.
