Puma — Puma one8 sneakers

I bought my one8 pumav3 shoes last 5months ago for my regular use, but it seems like the are going to cracles from side front sole is also cracked is just 5 months am not expecting this kind quality from puma, this is my first experience of buying a puma product. Although we have such companies like red tape, campus who gives better quality than puma so why should i trust on puma and why should i go with puma product when other brands give amazing quality in penny amounts. This is horrible
