I am looking for some guidance on sizing from folks who have purchased the Wave Sayanora. Reading lots of mixed opinions with many sizing down by a 1/2 size and others sticking with their "normal" running shoe size. I wear an 11 in most shoes - i.e. - Kinvara 3/4, Newton Distance, Brooks Pure Flow, NB MT1010. I would really appreciate feedback from those who have run in the shoe awhile. Thanks!
