Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Comfortable lace up shoes (e.g. sneaker) owned by the participant will be worn 2 weeks after surgery. The shoes will be worn while the patient is weight bearing, i.e. walking for any length of time. The shoes may be removed for sleeping or when the patient is not weight bearing. This will start at 2 weeks post surgery. This will be needed for at least unto 6 weeks after surgery. As these are the patient's own lace up shoes, they may continue to wear these in the future as they wish. The intervention will administered by the orthopaedic surgeon/staff in the clinic at their 2 weeks post surgery visit. The patient will be reminded to bring their shoes to this visit. Adherence will not be measured
Intervention code [1] 319306 0
Treatment: Other
Comparator / control treatment
Immediately post surgery, the patient will be placed in a stiff sole shoe (provided by the hospital) by the orthopaedic surgeon. The patient will be discharged with this stiff sole shoe. The patient will continue to wear this while weight bearing i.e. walking. This will be administered by the orthopaedic surgeon in the operating room after surgery. Adherence will not be measured

Eligibility
Key inclusion criteria
Patients between the ages of 18 to 80 (inclusive) undergoing 1st ray surgery surgery (either scarf and akin osteotomies for hallux valgus correction or first MTP joint fusion) will be recruited.

Summary
Brief summary
With novel surgical techniques and hardware design, plaster casts are not necessary to immobilise feet after 1st metatarsal surgery. Most surgeons support the use of a stiff sole post-operative shoe in either partial or full weight bearing to protect the surgical site and prevent complications over the course of 6 weeks post-surgery. We have previously demonstrated the use of rigid flat shoes improves satisfaction over the use of reverse camber shoe. The purpose of this study is to assess whether the use of comfortable shoes vs stiff sole shoes affects patient reported outcomes. Differences in long-term surgical outcomes of non-union and recurrence will also be investigated.
