VERY slippery inside my house on wood and linoleum so only purchase if you plan to wear outside. I unfortunately bought as indoor summer &#34;slippers&#34; and cannot use them as planned. I have no idea why FitFlop would have put the type of sole on this shoe that they did, it's actually quite dangerous as it feels like having ice-skates on. I may research and if there is another affordable basic sling style with a regular sole, I will purchase again as I love this brand so much. Maybe this shoe is a case of &#34;you get what you pay for&#34; as the price is lower than typical, and maybe this shoe was made to be worn for traveling to/from gym/pool/beach and taking the garbage out, etc. Otherwise the sling style is very cute, and the shoe is comfortable and stays on much better than the regular flop style.
