So I decide to "go pro" and get a decent running shoe. I go to my "local" store (run and become), which costs me £20 a time there and back. They are very professional, and watch me run back and forth in several pairs. I choose one that was comfortable for me, the Asics Gel Pursue 3. Now this came about from me explaining I do 10km uphill (albeit very slowly), and plan to do a triathlon in the future. I also explain my weak ankles, as I badly sprained both my ankles almost a year ago. I decide to run on them in the gym on the treadmill, at 15% incline. I get resistance from the balls of my feet and toes, which makes it really difficult. I decide to try 10km on the flat. 4km in, and my back goes.
I decide to take them back, so that's £40 on travel alone. I now explain EXACTLY what I want from the shoe (uphill on the treadmill), and what happened to myself while training. I then get told I need to run differently (not heel hammering), leaning forward as I run, while trying to push off with my toes and balls of my feet. After several pairs, I decide on the Saucony Guide 10s. I do the same again; try uphill first. Everything is fine, up until a few km in, when the balls of my feet and my toes are so painful I have to stop. The sweet sense of relief comes when I put on a flat shoe after leaving the gym.
So I go back again. I explain the problems I had, including aggravated ankles since I last came, and I get the New Balance M860. Yet again, I try them on the treadmill. Even walking into the gym with them on felt too hard on my heels (I'm still leaning forward and pushing off with my toes, for clarification). Everything felt a little bit different around my Achilles and ankles, but that passed. I take it real slow, 10 minute walk at 15% incline, 5.6 km/h. Now there's enough springiness to stop the balls of my feet from getting sore, but my back is going too painful uphill, which it never has before.
Now I can't fault the last two when it came to the flat, as I had a go on both. But I am getting sick and tired of going back and forth. Is it really hard to get a shoe that prevents back pain, protects my ankles, gives me enough padding on the balls and toes of my feet to make it comfortable, but minimum resistance making it easy to go uphill on the treadmill? My back also broke several years ago: I have screws in the 4th and 6th lumbar: four of them, held together like two staples in my back. I am posting this hoping there's some specialist here, that can figure out what shoe I need based upon what I have told so far.
