My shoes have arrived . . . slight dilema!

Double sided sticky tape Or toupee tape.

Mine have a similar back, can you not tighten the buckle? that worked for me

They fit on the lowest buckle hole as it is, it was my hope that I'd just be able to tighten the straps REALLY tight to keep them o. I did think about trying to get another hole made, but as they're satin I'm too scared they'll fray or be ruined somehow. I'm thinking of using something similar to insomniac03's suggestion above and using Scholl slingback tape and maybe ball of foor gel pads, just not sure with such a slim starp the sticky stuff will be very effective.

Usually you just tighten them enough and they stay on. You shouldnt have a problem making another hole if you want to try it just pull them tighter and thread the buckle without putting the tongue through if you see what i mean it should hold while you try it. It really is the only way to stop them slipping off. if you do make another hole make it fromthe outside with a darning needle first

You'll be fine making a new hole, but if you are worried, do it with a needle and try and aim between the threads of satin - if you dont break any then it cannot fray.

You just need to get more friction on the back of your heel, so anything sticky is good - it doesn't need to hold the strap still, just give it something to hold onto. So I'd put the tape onto your heel, not the strap.

Also, make sure the slingback is sitting high enough, it should be above the round of your heel, so at the skinniest bit of the back of your ankle.

If you post a pic of them on then I'll check. After that, its all just practice

Not sure you would want them too tight as your feet will warm up and swell slightly. You can get little gel inserts, I think they are called party heels from shops like Boots, and these would push your foot a little higher in the shoe. Don't know if this helps but might be worth a try.
