These shoes are great - narrow shoes are tough to find and these were what I was looking for. I absolutely loved this shoe. It fits how I imagined a small would fit, but the material is heavy and pulls the waistline down so it ends up looking a bit frumpy and all of the fabric overwhelms my frame. If you are not picky about this, the 700 Gen 2s are competent enough. The stainless steel is quite nice and ensures it stays intact. So cool it comes with 2 lid tops in 2 different colors😍 love it all the way and i am a picky person hahah so trust my words(: The extreme ups and downs placed enormous physical pressure on the flip-flops, but again, they were an extension of my body that never complained, so I took for granted their perseverance without a single protest. The wood bottoms are much heavier than the cork bottoms, so just be aware that you will not get the same shoe as pictured. I have incredibly sensitive skin as well and this has NEVER caused me any problems, only solved them FWAP!
