Hi Diana, If you're still holding onto beige as a neutral, then you'll love this new take: latte metallic brown. It's a warm and sophisticated neutral that coordinates with practically any color and design style. Best, Oofos

What is the heel cup like on these? I have lateral band plantar fasciitis, so the heel cup is as important as the arch support (if not more so).

The heel cup is great on these. I had tarsal tunnel surgery on my left ankle and this is the only shoe my foot will tolerate right now. Feels like you are walking on pillows. I love them! They are considered a recovery sandal for after surgery. I hope this helps.

How do you fit your foot into these so they don't make your arch hurt?

These do not hurt my arches, they actually helped when I had problems with plantar fasciitis. I wear them always around the house, I don’t walk distances in them. Maybe they just don’t suit your foot and gait??

talla: Tengo una confusión cuando ponen, por ejemplo: 11 Women/9 Men. Quiere decir talla 11 para mujer y 9 para hombre??

Lo que yo recomiendo es comprar los guaraches directamente por el website de offos. Mejores precios, no cobran por el envio, mejores estilos y tienen la talla specifica para hombre y mujer. Yo compre un size 7 para mi mama y no lo encontraba en Amazon.
