I think we all agree that shoes are important, but .. the fit.. Here is my rant..
Different sports has different .. needs. I used to wear cycling shoes that was "snug". It was about efficiency. As long as your feet do not go numb, it was good. I took that idea to extreme and rode sock-less for years because the narrow leather shoes does not have room for socks. I was young and stupid. On the same token, ballet slippers also need to be "form fitting".
When I finally got back to tennis, it took me some time and many black toes to realized that I need more room for my toes. I remember wearing K-Swiss tennis shoes in 80's. They were heavy but rugged, took some time to break in. But they were the least expensive full leather shoes at the time. I wore out a pair in a month during the season. Thank goodness the season was not that long.
Now a days, leather is no longer leather I learned. From a shoe maker, who ran shoe factory in China, "leather" may be made from leather fragments and reconstituted, kind of like particle board in lumber. That idea was a bit of shock, probably to you. Right, some leather was not made from one piece of hide but grind into small bits and essentially glued together. Sure it is leather but from many cows. Gosh!
Back to fit.. fit is highly personal. For a long time, I resisted buying online. But I gave it a try and found Prince Warrior to be super comfortable to my feet. I bought them again and again after I figured out the size I like. Guess what, it was plastic!? Like many shoes nowadays cracks on the either side of the forefoot, the upper I mean. When I keep the laces "snug", they still play pretty well even when cracked. I do not know, perhaps the 6-month guarantee sole is not a good idea for me, since I do not play that hard or so frequent any more. I no longer wear out the sole so easily, and the insole was probably bad. I do like putting good insoles in my tennis shoes when I have them. But it is getting about impossible to find the Prince Warrior shoes anymore. I hated the T-22, tried a few sizes and none worked.
Anyway.. I just need to remember to re-tighten my laces after warm up. Somehow my feet felt looser as I play. And I wonder how the "Greek god" break shoe laces.
