Now that summer has started I have been increasing my mileage from 6 miles a few times a week ( my commute) to 12- 15 mile daily minimum with 30 milers poking there head, except for rest and rainy days. I jst started this biking thing and am loving it but I do not want to invest a ton of money into it. I have been using my normal shoes a pair of Pumas that aren't even good enough for walking in for an extended period. When I assigned them as my biking shoes I thought it would be okay and even great to find a new use for this loyal shoes. Yeah that was stupid. However, I think that is why my arches and knees are hurting. I think I have caved the areas around the arches down and but a crack through the inside sole. I switched to my more thicker soled trail running shoes (and hiked my seat up a fair bit!) to try and relieve this pain but so far I don't think it is enough. I don't want to spend more money on shoes and on pedals than on what I paid for the bike and to boot I am still unemployed .

Is there anyway around buying the pedal/ shoe package or is there a way around it? I am increasing my mileage each week and don't want this pain to slow me down. Until I got serious for a century or something I wanted to stick with what I have. Any hints or thoughts?
