Sub-4 Clinic

Reviews

   My son and I recently visited Clifton at Sub4 to see if he could help address the ongoing physical issues my son has struggled with since the age of 13. He has just turned 19, and for years we’ve been trying to understand and resolve his persistent problems — including right leg patella pain, Osgood Schlatter’s, tibial micro-fractures, hip discomfort, and more recently, Achilles issues in both legs. His track and running ambitions had been significantly affected, despite rehabilitation, rest, and support from both NHS and private physiotherapy and orthopaedic routes. From the outset, Clifton took time to listen carefully, asking thoughtful and detailed questions about my son’s pain, discomfort, and training history. Following his thorough assessment and testing at the Sub4 premises, he identified a 5mm leg length discrepancy (LLD) in my son’s right leg and a pelvic tilt—factors that were clearly impacting his running form and performance. Clifton made a temporary orthotic during the session and had my son test it immediately on the on-site treadmill. The difference was instant and noticeable—my son immediately felt more balanced and aligned. We were extremely impressed by Clifton’s knowledge, enthusiasm, and precision. He demonstrated a deep understanding of the mechanics involved in running injuries and seemed to understand my son’s condition almost intuitively, confirming his observations through discussion and testing. It was the first time in years that someone truly seemed to connect all the dots and offer a clear, practical explanation. Clifton recommended custom orthotics, as well as strengthening and mobility exercises to support my son’s recovery and long-term performance. He has also been responsive to follow-up questions about running footwear, offering helpful and prompt advice beyond the initial appointment. After years of going through both NHS and private care without real answers, our experience with Clifton was a genuine breakthrough. I can’t tell others where to go, but in my honest opinion, if you or your child are dealing with similar persistent issues, I would highly recommend seeing Clifton at Sub4 before pursuing mainstream routes that often come with delays and generalised approaches. Even if you’re not sporty or an athlete, but experience issues with your feet, legs, posture, or general mobility, Clifton’s expertise means he can support individuals of all activity levels to move more comfortably and confidently.

   Went to see Clifton for a recurring achilles problem which turned out to be a leg length discrepancy which has now since been sorted out by the orthotics Clifton provided, during the session Clifton left me and my dad in awe with his knowledge and ability to diagnose my problem so fast, Clifton was also amazing with the follow ups for some minor alterations with insoles these been free of charge and no hassle, highly recommend seeing Clifton from an athletes perspective as his insight is other worldly.

   Personally i wouldnt go , there are others foot specialists like the foot doctor who really are experts , im suprised hes still going, went with serious ankle issues that were totally ignored and a sub standard insole recommended that looks like it was made around the back not sent off !! so ive wasted 6months + of getting better and thinking there is no solutions when there are !! dangerous really

   Had full assessment with Clifton at Sub-4 over 10 years ago. I have worn my custom designed orthotics every day since that time. As a result I have climbed mountains from Ecuador to Mongolia in complete comfort through desert, jungle and icy mountain conditions. I have had no problems with feet, knees hips or spine during this time - quite remarkable for a 78 year old. I can recommend Clifton and Sub-4 without reservation.

   Have been to a few places for orthotics and one actually caused injury gaining a hammer toe issue I never had before Having flat feet, with previous issues of fasciitis, now hammer toe, arthritic nodes in feet and neuromas I am again able to walk comfortably on feet after also having bi lateral hip replacements. The insoles/orthotics are amazing and actually stop my feet and rest of body hurting or getting worse Thanks Clifton

   I've been a patient here for over 15 years, and I've worn Sub-4 orthotics continuously each day in that time. I attend for a review and prescription update every 18 months or so and get a new set of orthotics. In that time the orthotics have protected me from back, leg, ankle, knee issues which have been well controlled. I can't recommend Sub-4 highly enough.

   Clifton is a top level resource for injury prevention. I was a professional Olympic level athlete and travelled to see Clifton several times. He was a huge help to my career and came across as a real expert in his field. I would for sure recommend him to anyone.
