When you have hammer toes, or toes that are contracted and tend to curl under, it is recommended that you choose a shoe that has a wider toe box.  A shoe with a narrow toe box can aggravate hammer toes.  They may rub on the top of your toes, causing areas of thick skin buildup (corns) or blisters, or even worse, an open wound especially in diabetic patients who may have less feeling in their toes due to neuropathy.  So be good to your feet and stay away from the pointy toes shoes!
