Since I cannot access the video here... I have no idea what you are talking about... but it sounds intriguing... WHY is there an extra hole?
Hey!! I went for my walk last night and I actually used the heel lock.. BUT to really try it out I used it on only one shoe and the other I tied the regular way.. Guess what... It REALLY REALLY makes a difference. I have very well fitting walkers, but I could tell there was less sliding of my foot in the one with the heel lock. It felt more stable.. SO I will be using it (on both feet) from now on.
I haven't tried it yet, but just did so while watching the video. Got them all looped for tomorrow for the gym. But I can feel they will be more secure.
I'll still probably never make use of the extra shoelace holes in my sneakers, but if I was still jogging for exercise, I might give it a try. Did you know this??
Merlin, I've nearly left home in slippers!
I can never wear cheap trainers with my flat feet and plantar fasciitis flare-ups. My son got severe plantar fasciitis when he was 40 because he was wearing cheap shoes playing basketball.

I luckily have never had problems with my feet, but since becoming older I do spend more on shoes, and buy Merrells these days. The ones I have are so supportive and comfortable, its just like wearing slippers, which is why I often forget to change, I think I already have shoes on

This is the style I wear

Holly, there is a chain of shops in Scotland called Runforit that my stepdaughter went to when she started running. They did a thorough free assessment on her feet, gait, pronation, etc and recommended what type of shoe she needed. Must be a similar shop in your area?
