While walking in heels, put your heel down first followed by your toe. This is a more comfortable and natural way to walk in heels
Instead of wearing a new pair of heels directly to a party or an event, break into them at home first. This will make it much easier for you to walk in heels outside
Lean back a little bit while walking in heels to maintain your balance. Take smaller steps and walk slower than usual when in heels
Try to place one foot directly in front of the other in order to walk in a straight line. It gives your walk a more graceful look, especially when wearing heels
Just in case you do not feel comfortable walking in heels, take support and come prepared. You can use insoles, heel grips, band-aids, extra cushioning, etc to give you confidence initially
