Prepare a cup of 70°C hot water, put the small end of the engine in warm water and turn the flywheel to give its initial speed, so that the engine begins running.

Sandles
Size: 5, Color: French Sand
Love the shoes so pretty but, the strap hurts my little toe but today was first time wearing so I'm hoping I just got to wear them a few times and break them in.. A friend has a pair and she loves them. She said they are very comfortable.

Do recommend
Size: 9, Color: French Sand
Obsessed with these shoes! They are the perfect classic nude heel. I hate the thick heel on a lot of nude shoes and this one is so different in the best way. It looks like a stiletto from the side, but as we know you get much more support. I think you do get your value for the money you spent, these were expensive but they are long-term durable heels. They are comfortable and the sizing is accurate. I’m a 9 and they fit me perfectly.

Beautiful comfortable heel
Size: 7, Color: Amber Gold
Love these shoes! I wore to a wedding without breaking them in and my feet didn’t start to hurt until 9 hours into the event! I am usually between a 6 and 6.5 and got a 6.5 and they fit perfectly.
