They run a little large but not to bad to send them back. I wear them almost every day and I have no complaints. The sounds of the drums, the tight sound of the snare, the depth of the tom toms and floor toms and the crystal clear sound of the cymbals are very present. Did not contact seller. I also like the lacing system which allows for easy removal which my consumer boots dont have. Bought this half the price was a very great deal for me as a parent. Even those he wears sockless like crocs and nike sandals. The new soft footbed technology is awesome. I orderded this one primarily for the capability of connecting two devices simutanously. Im very disappointed it stop working after only 6 month.
