Feel painful when use force fin pro

[WAI SHING LUNG]

Make a nice round or oval hole in the fin on top of the affected location

Thanks for ur advice. I tried to wear a thick sock with my diving shoes last week and seems much better. My feet no more hurt or just a little bit feeling when fins but my instep still feeling good after 2 dives. I think the pocket is too hard, and thats ok if wear a thicker protection. anyway... i think it is solved now. Thx
