Wide toenails can be caused by a variety of factors, from fungal nail infections to long-term conditions such as psoriasis. They can also be a result of wearing shoes that are too small or too narrow. In some cases, wide toenails may be a sign of a more serious medical condition, such as liver cirrhosis or iron-deficiency anaemia. While there are treatments available, such as wearing wide-toe shoes, keeping nails trimmed and clean, and getting exercise, it may not always be possible to prevent wide toenails.

Wide toe nails can be a sign of reactive arthritis
Wide toenails can be a sign of onychauxis, a toenail disorder. Onychauxis can be treated by wearing comfortable, wide-toed shoes, and keeping your nails trimmed and clean. It can also be a good idea to boost circulation in your lower extremities by walking, riding a bicycle, or otherwise moving more.
Onychauxis has been linked to reactive arthritis, a poorly defined disorder that has been described in the medical literature under many different names. Reactive arthritis is a general term for a form of joint inflammation (arthritis) that develops as a "reaction" to an infection in another area of the body (i.e., outside of the joints). Joint inflammation is characterised by redness, swelling, pain and warmth in and around the affected joint. In reactive arthritis, the large joints of the lower limbs and the sacroiliac joints are most often affected. Reactive arthritis belongs to a group of inflammatory arthritis conditions called spondyloarthritis.

In the meantime, there are a few things you can do to help manage wide toe nails. Wearing wide-toe shoes can help reduce pain and discomfort caused by your nails rubbing against your shoes. Keeping your nails trimmed and clean can also help reduce the risk of nail disorders.
