Most shoes will likely fit perfectly first time and will stretch slightly after more than 4 wears.                                                                             

If you are in between a half size (a 9.5-10 like me) choose the size up.  So I wear a size 10.       



Tiva Slides - in this style, if you are a half size, choose the size up. 

For example a 9.5 size, Choose a 10. 

This slide is a smaller make however will stretch after wearing to be perfect! 

They may seem small initially but hang in there for some stretch, this way they don't feel like they are going to fall off your feet if you get a size too big.                                                                                                                                       

Variado enclosed shoe - this shoe has a long pointed toe.  I am a 9.5-10 and I found I liked the size 9 and the fit was good. I would consider my foot to be a little wide. They will stretch after some wearing. No need to wear socks with these ventilated all leather babes!
