Seven guidelines for securing an excellent athletic shoe

Determine the type of athletic shoes you plan to buy (running, tennis, soccer, etc.). As a rule, if you plan to participate in a specific sport activity three or more times per week, it is probably wise to purchase a shoe specific to the sport.

Locate a reputable shoe store that offers a variety of sports specific shoes and staff that are knowledgeable, helpful and willing to spend time with you to assure an appropriate shoe purchase. Check the store's return policy before your shoe purchase.

Before going to the store, be sure you have the following information which will help the salesperson find the appropriate shoe for you: a) injury history; b) old shoes (check wear pattern); c) weight; and d) foot type/shape.

Consider the following points to assure proper foot measurement: a) visit shoe store after a workout; b) have shoes fit with socks you intend to wear; c) bring any shoe inserts and put them into shoes; d) use Brannock device for measuring both feet with socks on - both sitting and standing; e) three measurements should be taken: heel-to-toe, heel-to-ball, and width; f) measurements should only be used as a guide!

Consider the following points to test for proper shoe fit: a) allow 3/8 to ½ inch between longest toe and end of toe box which should have ample height and width to accommodate toes; b) ball of foot should match widest part of shoe with "bend" of toes matching toe break of shoe; c) assure adequate space across ball of foot by dragging your thumb across vamp (front part) of shoe; d) heel fit should be snug; e) match your arch without construction or discomfort; f) wear test shoes in store to assure fit and balanced, comfortable gait.

Thoroughly inspect the inside and outside of shoe for defects and blemishes. Place shoe on firm, flat surface and make sure heel is straight and shoe is stable.

Periodically check shoes for excessive wear. A new pair of shoes should be considered if 1) outsole is worn to level of midsole; 2) heel counter is tilted excessively either in (everted) or out (inverted); 3) forefoot upper is "falling off" (overlapping) inner or outer aspect of the outsole; or 4) persistent injuries possibly due to inadequate midsole cushioning
