Left shoe fits better than the right.  Not sure why.  Definitely noticed a difference in my oly lifting, although I wasn't using oly shoes prior to these, and having nothing to compare them to prior.  Back squat went from 285 to 315 after 3rd time using shoes.  From squat went from 225 to 265 in same time period.  Snatch is definitely more comfortable as well as overhead squat.  Not sure that baking them really made a difference....IDK.  Overall, I like them.
