Need shoes

I need new shoes. It's not even a question of wanting new shoes anymore. NEED them.
I did the same thing as last week, ran home from work. I ran the 7K a little bit faster this week -- probably owing to the perfect running conditions (low 20Cs, slight breeze, bit of sun vs 30C+ and extreme humidity and smog alert) -- and despite really feeling the unbounciness of the shoes. Indeed, I've had this particular pair of shoes, New Balance 1222s, since mid-August last year. It's time to retire these ones before I hurt myself. I already think I'm feeling something....
