Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.205.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 12:56, 12 May 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Forensic podiatry''' is a subdiscipline of [[forensic science]] in which specialized podiatric knowledge including foot and lower-limb anatomy, musculoskeletal function, deformities and [[diseases of the foot]], [[ankle]], lower extremities, and at times, the entire human body is used in the examination of foot-related evidence in the context of a criminal investigation. Forensic Podiatry has been defined as:

((quote|The application of sound and researched podiatry knowledge and experience in forensic investigations, to show the association of an individual with a scene of crime, or to answer any other legal question concerned with the foot or footwear that requires knowledge of the functioning foot.((r|VernonMcCourt1999))))

Those who specialize in this field need to have gained knowledge and experience in podiatry and also in forensic science and practice.((r|VernonETAL2009))

Forensic podiatry is usually used to assist in the process of [[Forensic identification#Human identification|human identification]], but can also be employed to help address issues relating to questions that have arisen within the context of forensic enquiry. Such questions could include whether or not a shoe could have had multiple wearers, what the effects of a shoe not fitting correctly could have been, whether or not someone could have placed their foot into a shoe that was too small for the postulated wearer's foot and other matters involving the podiatric interpretation of relevant evidential materials.

==Areas of practice==
There are currently four areas of forensic podiatry practice. These usually involve the analysis and interpretation in a forensic context of:((r|DiMaggioVernon2017))

*Bare footprints (both static and dynamic prints)
*Footwear (specifically the consideration of features of wear and fit)
*Podiatrists' clinical records
*[[Gait analysis]] (usually covering the examination of the gait forms of persons captured on closed circuitry television [CCTV], but also covering the analysis of the sequences of footprints at a crime scene)

==Methods==
Forensic podiatry techniques usually follow the ACE-V approach used widely in forensic science and practice.((r|DiMaggioVernon2011)) Here, ACE is the acronym for the analysis, comparison and evaluation of an item of evidence with exemplar or reference material (such as a shoe, bare footprint or recording of a suspect's gait). Verification is about the independent working through of that same material by a peer forensic specialist to confirm whether or not they reach the same conclusions as the reporting specialist.

Physical evidence is generally understood to exist at two levels which have been described as demonstrating class and identification level characteristics.((r|DiMaggioVernon2017)) Class level characteristics demonstrate consistency and compatibility, not uniqueness, which identification level characteristics are those which are understood to be unique (REF). Forensic podiatrists currently work with class level features alone although some of those features can demonstrate high levels of individuality.((r|DiMaggioVernon2017))

Given that forensic podiatrists currently deal with class level characteristics alone, their work would not in itself usually result in the incontrovertible identification of someone unless the situation is one in which a closed population (that is one in which there is a limited number of possible people to consider when considering the possibility of a match or mismatch between two evidential items from a podiatric perspective).

The evidential materials that would be considered by forensic podiatrists can sometimes fall within the specialist understanding of other disciplines. For example, forensic gait analysis case work has been undertaken by human movement scientists and the knowledge involved in forensic gait analysis is that possessed by some physical therapists and orthopedic specialists as well as podiatrists.((r|DiMaggioVernon2017))

Similarly, some evidential material of interest to forensic podiatrists is also of interest to other forensic specialists (particularly forensic marks examiners) although from their own particular perspectives((r|DiMaggioVernon2017)) and forensic podiatrists always need to consider the potential for multidisciplinary considerations/collaborations.

==Key historic developments==

In 1937, [[Sydney Smith (forensic expert)|Sir Sydney Smith]], examining a pair of shoes left behind at the scene of a burglary in [[Falkirk]], made deductions about the suspect.  In spite of the suspect's agility as a [[cat burglar]], he suggested that the suspect was short, had a left leg shorter than the right, a left foot an inch shorter and half an inch narrower than the right, had limited mobility in his left leg and was missing the fourth toe on that foot.  He also suggested that the criminal would have a severe lateral spinal curvature. After a man was arrested [[in flagrante delicto]] at the scene of another cat burglary, and convicted, he allowed Smith to examine him in prison.  

Smith discovered that he was five foot three, had had infantile paralysis in his left leg, that the leg was withered as a result, that his deductions about the size of the foot and leg were correct, but that the spinal curvature was less than he suspected.((r|Smith1959_3104))

In 1972, Norman Gunn, a podiatric physician from Canada, was the first podiatrist worldwide to undertake forensic podiatry case work.((r|Vernon2006))

In 1989, Wesley Vernon, a podiatrist from the UK, began to undertake research in forensic podiatry and later began to undertake case work from the mid 1990s.

In the early 1990s, John DiMaggio, a podiatric physician began to undertake forensic podiatry case work in the US.

In September 2003, an organization was formed – the American Society of Forensic Podiatry.

In 2007, the Council for the Registration of Forensic Practitioners (CRFP) developed a competency test for forensic podiatrists in the UK. The CRFP is no longer in existence, but this testing process was developed further by the [[Chartered Society of Forensic Sciences]] in the UK and is available for those practising in this field.

In July 2007, a forensic [[podiatry]] science and practice subcommittee was established within the structure of the [[International Association for Identification]] (IAI).

In 2009, the IAI published a document defining the role and scope of practise for forensic podiatrists.((r|VernonETAL2009))

In 2011 an M-level course in forensic podiatry was developed at the University of Huddersfield in the UK. This was later developed further into a full MSc course in forensic podiatry at that university.

In 2011, the first forensic podiatry textbook was written.((r|DiMaggioVernon2011)) In 2017, a much more comprehensive, updated 2nd edition of this book was published.((r|DiMaggioVernon2017))

In 2013 a forensic podiatry group was started at the [[New York College of Podiatric Medicine]].

In 2013, a student forensic [[podiatry]] group was started at [[Temple University School of Podiatric Medicine]].

In 2014, the forensic podiatry approach to bare footprint analysis was found to meet the US the United States Supreme Court's standard of admissibility through a Daubert hearing.((r|Nirenberg29Feb2016))

==Contemporary developments==

In 2016, a forensic podiatry club was started at the Barry University School of Podiatric Medicine.

A formal class covering aspects of forensic podiatry is being held at [[New York College of Podiatric Medicine]] (open to [[podiatrist]] candidate)s. Students exit the class with an in depth knowledge of forensic podiatry and other legal knowledge applicable to current cases.

In 2017, at the behest of the UK regulator for forensic science, standards of practice for forensic gait analysis are being written and at the time of writing a draft document has been put out for consultation. It is anticipated((whom|date=July 2023)) that these will be completed in early 2018.
