I don't know exactly what you mean by that question, but perhaps "an equal distribution of the polar bear's weight amongst its 4 extremities" is what you're looking for?

Polar bears have large paws compared to body size, paws of a polar bear act like snowshoes, spreading out the bear's weight as it moves over ice and snow.

Hello,
A Polar bear attempts (doesnt always succeed though) to avoid falling through very thin sea ice by spreading its legs & paws as wide as it can, by doing this it can distribute its weight over a wider area and this does infact work to prevent it falling through the ice.
**But having seen polar bears do this on film, it does appear to have its limits and they do eventually end up in the water.
**Remember though that polar bear's are infact excellent swimmers and are quite at home in the polar (artic & antartic) sea's and they will swim many miles across open water to find the next meal.

Sometimes they do, they don't mind. Like taking a bath for them
as long as thier is someplace solid for them to get back out on.
That is the scientist only fear with global warming, that polar
bears will drown if all the ice melts. Thier population is already
being cut down do to this.

theyve got huuuuge paws which distribute their weight evenly over the ice. Although i dont think that there is thin ice in the artic.
but if they do fall through, they can swim in freezing waters.

I herd that polar bears are one of the only mammals that have webbed feet. I bet they do fall through sometimes....

They watch their step; after all, they have a lot of chances to learn to spot thin ice.

they only eat helium-filled seals
just kidding
they don't avoid it
in fact, many polar bears are now drowning due to global warming

Their paws spread out to distribute their weight evenly which makes it harder to break the ice.

massive paws - good weight distribution over the ice.
