Did The “Low Price” runners work??

No ……….. No they didn’t. But why didn’t they? Was it the runners (http://kehoephysio.me/2015/01/28/the-low-priced-runners-arrived/) or did I ever believe it was possible that they would be as “good” as my  more expensive  runners. I covered just under 300km in the cheaper runners – I gave them a chance! But I started getting bilateral achilles pain, particularly on the longer runs – greater than 20km. I have never had this  problem. My legs were heavier and my times much slower (not that they were ever too quick).

 

"Low Priced" weigh in  300 grams
“Low Priced” weigh in 300 grams
"my normal runners"
“my normal runners” – 190 grams

So my legs felt heavier – but were they? Yes they were,  by over 100 grams per shoe. Not much you think? YES it absolutely is!!! Studies have consistently shown that heavier shoes reduce running economy. Each 100g/3.5oz added to the weight of each shoe reduces running economy by about 1% (Fuller et al., 2014).  The literature would suggest that my choice of runner has no influence on my injury (Lieberman et al., 2010; Goss & Gross, 2012). But lets consider the other most  noticeable measurable effect was a slowing in my running,  caused by the cheaper runners,  this may have contributed  to my achilles pain by inadvertently affecting my foot strike and reducing my cadence ( steps per minute) (Wellenkotter et al., 2014).

 

Runners - cut in half
Runners – cut in half

I will return to searching amazon and my other regular haunts looking for deals. The endless search for the best runner continues, I may never find it but I will enjoy the hunt and will continue to hide my new runners from my wife!

I qualified with an Honours degree in Physiotherapy from Trinity College Dublin in 2004. Since graduating I have worked in St. James Hospital Dublin and have worked in all the areas of speciality within the hospital including cardiorespiratory, orthopaedics, rheumatology, care of the elderly, neurology, burns and plastic surgery among others . I have also completed a post graduate certificate in acupuncture in UCD 2009. The Physiotherapy Department in SJH has strong links with Trinity College Dublin (TCD) and I have supervised undergraduate and postgraduate physiotherapy students on practice placements and also delivered lectures on the undergraduate academic programme in TCD. I have a keen interest in all sports and currently plays with Cill Dara RFC 1st team squad, and Milltown GAA. I have previously worked as Physiotherapist to Co. Carlow Senior GAA Team, Milltown GAA, Leinster Junior Rugby Team and Cill Dara RFC. I am an experienced runner and competed in the Dublin City Marathon in 2002. I continue to participate in running events and multisport disciplines such as Gaelforce West, Gaelforce North and the Motivate Challenge. I have a particular interest in strength and conditioning. I utilise this knowledge of resistance training in the treatment of his clients. I am committed to continuous learning and development in order to ensure the optimal level of care is offered to my clients, and with this in mind I am currently undertaking a certification in Strength and Conditioning (CSCS) with the NSCA.
