9.50 oz Heel Stack:40.5mm Forefoot Stack:35.5mm Hoka Women's Bondi 9 Running Shoes As an OR RN I an on my feet literally all shift ( including the footwork needed to maneuver stretchers ). The Bondi shoe takes the beating day after day and supports my feet in style. I have worn Bondi 7. & now the Bondi 8 for years. I bought these on Saturday 5/17. I normally walk 10K steps a day. no running. The tread and bottoms are already ripping/ rubbed off. Also rubs the side of my toe horribly. First and LAST time I'll purchase this brand.
