Wearing through tennis trainers.
I am a regular player and play for about 10 hours every week. I find myself spending a large amount of money on new trainers every few months and am not sure why they seem to wear so quickly. They always wear in the same place which is where the end of my big toe is on my right foot. Please help as trainers are not cheap and I would much rather spend the money on rackets and balls! Any suggestions on the cause and ways to avoid this would be highly appreciated.
