Here is a link to a footpeg offered on amazon.ca. I'm sure you will find them on the american site if you look hard enough. If not, they might ship it to the US.https://www.amazon.ca/dp/B00RUQ9V8O/?col...lv_ov_lig_dp_it
They charge 67$ CAD with free shipping. That's under 52$ USD today and they have good reviews.
Those will not fit the XT225. On the XT225, one side is significantly different than the other, as seen here http://www.xt225.com/forums/ubbthreads.php?ubb=showflat&Number=74345&#Post74345
The fact that the Amazon listing includes both the XT225 and the XT250 in the list of models, shows that the seller is in error. Footpegs that are compatible with the XT250 are not compatible with the XT225.
EDIT: Looks like one buyer already realized it and gave one star:
