For the shoes below, the left side fits my left foot beautifully and they are very comfortable to wear but after walking for a while I find that my right foot hurts because the right side is just too tight and squeezes my right toes. As you can see from the picture below, it is a UK size 2 shoe. So into the shoe cabinet they went never to be seen again.
When I first tried on the pair of shoes below in the shoe shop, it felt great so I bought them but when I came home, I found that the left side is just too loose although the right side fits nicely so I bought some insoles to pad up the left side but still find it not comfortable to wear so for two years now this pair has never been worn even once. As shown in the picture below, it is a size 3 shoe. I am not sure whether the size refers to a UK or US size. What a waste of money.
This pair below is my favourite pair of sandals. I tend to be heavy on my right leg while walking so the right side was worn out way before the left side and I have to say goodbye to them. This pair is a size 4. I am also not sure whether it is referring to the UK or US size. They only served me for less than 1 year but I wore them almost everyday everywhere I went.
The sport shoes below are slightly larger than my feet as it is a UK size 4.5 but they are very comfortable to wear and they have served me well as I wore them for the whole 15 days of my Kyoto-Osaka trip last year. They were the only shoes I brought on the trip and I was really walking a lot then.
Now it's time for me to buy a new pair of shoes as I have no other pair of shoes apart from those displayed here. I am just wearing slippers from the night market as a temporary measure for the time being. Hopefully this time, I will be able to buy a comfortable pair that fits both my feet not only in the shoe shop but also when I come home. With US, UK, and EUR sizes, I really do not know what my shoe size is. I suspect my left foot is a UK size 2 and my right foot is a UK size 3. Now where can I find a shoe shop that is willing to sell me mix and match sizes, I wonder.
