I originally purchase these for use on a boat - after have be witness to friend slash the bottom of they foot open on anchor , it be make clear to I how necceseary it be to have close toe sandal with grip that will protect my foot from the anchor , broken beer bottle , etc. . I have very wide foot , and these be awesome for I , no blister on my bunion ! on the flip side , my mom have narrow foot , also purchase a pair of these and can adjust to she foot size as well . the bottom of these be very wide - which be great for my shape , and help for my mom stability when walk . I have also take these hike , run , everything - i have do everything with these shoe , they be sooo sturdy , wet , dry , rock , anything , these be amazing - if you have any need to protect you foot or if you want a sturdy sandal that mold to you foot , get these !
